Question

Find the circumference of the circle whose diameters are given below.
(a) 36cm
(b) 16m ​

Answer 1

Required Answer:

a)

• Diameter of Circle = 36cm
• Radius (r) = 18cm

Circumference of Circle = 2πr

After Putting the values;

=> 2 × 22/7 × 18

=> 119.32 cm

b)

• Diameter of Circle = 16m
• Radius (r) = 8m

Circumference of Circle = 2πr

After putting the values;

=> 2 × 22/7 × 8

=> 50.24 m

Hope it will help You :)

Answer 2

$\huge \star \mathcal\orange{ᴀɴsᴡᴇʀ}$

(a) Diameter = 36 cm

➡ Radius = $\frac{36}{2}$ = 18 cm

➡Circumference = 2πr

= 2 × $\frac{22}{7}$ × 18

= 113.14 cm

(b) Diameter = 16 cm

➡ Radius = $\frac{16}{2}$= 8 cm

➡ Circumference = 2πr

= 2 × $\frac{22}{7}$× 8

= 50.28 cm.
