Question

What is the area of the following circle?

Answer 1

49π or 153.86

Explanation:

Hi there,

The formula for area of a cirlcle is A =
`\pi`
`r^(2)`

So, to find the area, simply plug in the radius into the equation.

A = π *
`7^(2)`

A = 49π

The area is either 49π or if you use 3.14 for pi, it's 153.86.

Hope this helps!

Answer 2

A=153.938 or 154

Explanation:

A= pi r^2

A=pi(7)^2

A=pi(49)

A=153.938 or 154
