Question

Find the following measure for this figure.

Area of circle =

6 square units
12 square units
36 square units

Answer 1

The correct answer is 36π square units

Explanation:

Points to remember

Area of circle = πr²

Where r - radius of circle

From the figure we can see a circle with radius 5 units

To find the area of circle

Area = πr² = π * 6² = 36π square units

Area of given circle = 36π square units

Therefore the correct answer is 36π square units

Answer 2

Answer: Last option.

Explanation:

The formula for calculate the area of the circle is the shown below:

`A_c=r^2\pi`

Where r is the radius of the circle.

As you can see in the figure attached, the radius of the circle is 6 units, then:

`r=6units`

Therefore, when you substitute the value of the radius into the formula shown above, you obtain the following result:

`A_c=(6\ units)^2\pi`

`A_c=36\pi\ units^2`
