Question

4. Find the circumference of the circle whose diameter is :
(i) 77 cm (ii) 10 m (iii) 4 m
(iv) 70 cm
Find the circumference of circles whose radius is :
(i) 3.5 cm (i) 5.6 cm (iii) 2.1 cm (iv) 9.8 ​

Answer 1

Answer:

(i) diameter = 77 cm

radius = 77/2 = 38.5 cm

circumference of circle = 2πr

= 2× 22/7×38.5

= 242cm.

isi tarah se question no. 4 ke saare parts honge

Q2 (i) circumference of circle = 2πr

= 2× 22/7× 3.5

= 22 cm.

baaki ke parts bhi aise hi honge agar koi confusion ho to pooch lena.
