Question

Find the area of the circle. Use 3.14 for it. E d = 10 cm A = [?] cm2 A=7tr2​

Answer 1

Answer: d=10cm

According to the formula i.e. A=πr²

first we need 'r'

as r=d/2

hence, r= 10cm/2

r=5cm

put r=5 in formula

=3.14(5cm)²

=3.14×25cm²

=78.5cm²

Answer 2

A=(78.5)cm²

Explanation:

d=10

r=10/2=5

A=πr²

A=3.14*5²

A=3.14*25

A=78.5cm²
