Question

Find the area of each circle. Round to the nearest tenth.

Meet some help with this

Answer 1

`84.9 \ yd^2`.

Explanation:

Given:

Diameter of the circle = 10.4 yd

So we will find the radius of the circle.

radius of the circle is equal to half of the diameter.

So,

radius (r) =
`(diameter)/(2)=(10.4)/(2)=5.2\ yd`

We need to find the area of the circle.

Solution:

Now we know that;

Area of the circle is equal to π times square of the radius.

framing in equation form we get;

Area of the circle =
`\pi r^2 = \pi * {5.2}^2 = 84.9 \ yd^2`

Hence Area of the circle is
`84.9 \ yd^2`.
