Question

Find the area of the circle with following radii (take π=22/7). a. 28cm. b.14cm. c.7/2cm. 42cm

Answer 1

Answer:

Step-by-step explanation: a) use formula A= pi*r*r

where r=28 cm

A= 22/7*28*28

  =2464 cm^2

do these for other numbers too.

Answer 2

(a). area of circle = 22/7 x 28 x 28

= 2464 cm^2

(b) = 22/7 x 14 x 14

= 616 cm^2

(c) = 22/7 x 7/2 x 7/2

=38.5 cm^2

(d) 22/7 x 42 x 42

= 5544 cm^2

hope it's help you ✌✌✌
