Question

Find the following measure for this figure.
Area of circle =

6 square units
12 square units
36 square units

Answer 1

Answer: Last option.

Step-by-step 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:

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

$A_c=36\pi\ units^2$

Answer 2

Answer:

The correct answer is 36π square units

Step-by-step 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
