Question 69.
A rule for locating the approximate size of diagonal of a sq. is to multiply the size of a aspect of the sq. by 1.414. Discover the size of the diagonal when :
(a) The length of a aspect of the sq. is eight.three cm.
(b) The size of a aspect of the sq. is strictly 7.875 cm.
Answer:
(a) Size of a aspect of the sq. = 83 cm
∴ Length of the diagonal of the square
= 1.414 × eight.three cm = 11.7362 cm
≈ 11.74 cm
(b) Size of a aspect of the square = 7.875 cm
Size of the diagonal of the square
= 1.414 × 7.875 cm
= 11.13525 cm
≈ 11.14 cm

Question 70.
The most important sq. that can be drawn in a circle has a aspect whose size is Zero.707 occasions the diameter of the circle. By this rule, discover the length of the aspect of such a square when the diameter of the circle is
(a) 14.35 cm
(b) eight.63 cm
Answer:
(a) Diameter of the circle = 14.35 cm ..
∴ Length of the aspect of the square
= Zero.707 × 14.35 cm
= 10.14545 = 10.15 cm
(b) Diameter of the circle = 8.63 cm
∴ Length of the aspect of the sq.
= 0.707 × eight.63 cm
= 6.10141 cm = 6.10 cm

Query 71.
To seek out the space round a round disc, multiply the diameter of the disc by three.14. What’s the distance around the disc when :
(a) the diameter is 18.7 cm?
(b) the radius is 6.45 cm?
Answer:
(a) Diameter of the disc = 18.7 cm
∴ The space around the disc
= 3.14 × 18.7 cm = 58.718 cm
(b) Radius of the disc = 6.45 cm
∴ Diameter of the disc = 2 × 6.45 cm = 12.9 cm
∴ The space across the disc
= three.14 × 12.9 cm = 40.506 cm

Question 72.
What’s the cost of 27.5 m of fabric at ₹ 53.50 per metre?
Answer:
Value of 1 metre of fabric = ₹ 53.50
∴ Value of 275 metres of fabric = ₹ (53.50 × 27.5) = ₹ 1471.25

Query 83.
In her science class, Jyoti discovered that the atomic weight of Helium is 4.0030; of Hydrogen is 1.0080; and of Oxygen is 16.0000. Find the difference between the atomic weights of:
(a) Oxygen and Hydrogen
(b) Oxygen and Helium
(c) Helium and Hydrogen
Answer:
Atomic weight of Helium = 4.0030
Atomic weight of Hydrogen = 1.0080
Atomic weight of Oxygen – 16.000Zero
(a) Difference between the atomic weights of Oxygen and Hydrogen
= 16.0000 – 1.0080
= 14.9920
(b) Distinction between atomic weights of Oxygen and Helium = 16.000Zero – 4.0030 = 11.9970
(c) Difference between atomic weights of Helium and Hydrogen = 4.0030 – 1.0080 = 2.9950

Question 84.
Measurement made in science lab have to be as accurate as potential. Ravi measured the length of an iron rod and stated it was 19.34 cm lengthy; Kamal stated 19.25 cm; and Tabish stated 19.27 cm. The right size was 19.33 cm. How much of error was made by every of the boys?
Answer:
The right size of the iron rod = 19.33 cm
The size of the rod measured by Ravi = 19.34 cm
∴ Error made by Ravi = (19.34 – 19.33)cm = +0.01 cm
The length of the rod measured by Kamal = 19.25 cm
∴ Error made by Kamal = (19.25 – 19.33) cm = -Zero.08 cm
The length of the rod measured by Tabish = 19.27 cm
∴ Error made by Tabish = (19.27 – 19.33) cm = -Zero.06 cm.

Query 87.
A flooring is 4.5 m lengthy and 3.6 m large. A 6 cm square tile prices ₹ 23.25. What would be the value to cover the ground with these tiles?
Answer:
Size of the floor = four.5 m
= (4.5 × 100) cm = 450 cm
Width of the ground – three.6 m – (three.6 × 100) cm = 360 cm
∴ Area of the floor – (450 × 360) cm2 = 162000 cm2
Aspect of a sq. tile = 6 cm
∴ Area of 1 square tile = (6 × 6) cm2 = 36 cm2
Number of tiles reqnuired to cowl the ground

Question 116.
Sports activities: Reaction time measures how Questionuickly a runner reacts to the starter pistol. Within the 100 m sprint at the 2004 Olympic Video games, Lauryn Williams had a reaction time of 0.214 second. Her complete race time, including response time, was 11.03 seconds. How lengthy did it take her to run the precise distance?
Answer:
Complete race time of Lauryn Williams = 11.03 seconds
Her reaction time = 0.214 second
∴ Time taken by her to run the precise distance
=(11.03 – 0.214) seconds = 10.816 seconds

What was the scholar’s error?
Answer:
Since Zero.three is bigger than Zero.25.
∴ -0.three is less than -0.25
∴ The error is -0.30 >-Zero.25
