Question

Find the area of the circle. Use 3.14 for tt. d = 6 ft A = [?] ft2 A=Tr2​

Answer 1

d=6ft

According to formula A=πr²

first we need 'r'

Hence,

as, r=d/2

r=6ft/2

r=3ft

A=πr²

A=3.14(3ft)²

A=3.14×9ft²

A=28.26ft²

Answer 2

I know that the diameter is double of the radius, so I can divide 6 by 2 to get 3. 3.14(3)^2 gives me 28.26.
