​

Answer 1

Answer:

154 sq cm

Step-by-step explanation:

Taking pi as 3.14 will give an approximate answer. You can do it by taking 22/7 as well

Let the radius be r cm

Circumference will be,

2 r = 2 * 3.14 * r= 6.28r

ATQ,  6.28r- 1r =37

5.28r = 37

r= 37/5.28

r= approx. 7 cm 

Area=  r² =  3.14 * 7 * 7 = 154 

Answer= 154 sq cm
