Question

If the diameter of a circle is 16 in what is the area in terms of pi​

Answer 1

`64\pi`

Explanation:

diameter => D = 2r

r = D/2 = 16/2 = 8

area =

`\pi * r {}^(2)`

=

`64\pi`

Answer 2

Explanation:

According to the Question , diameter of circle is 16 inches. We need to find the area in terms of pi (π) . We know the area of circle as product of pi and square of radius . Therefore ,

`\to\tt \orange{ Area = \pi r^2 } \\\\\tt \to Area = \pi (8 \ in.)^2 \\\\\tt\to \boxed{\orange{\tt Area = 64\pi in^2 }}`
