Ian needs to find area of the shaded region shown below. Which statements can he use to find the answer?

The radius is 5.5 feet.

The area of the whole circle is A = (5.5) squared pi.

The area of the shaded region can be found by multiplying the area of the whole circle by three-fourths as in A = three-fourths (pi times r squared).

Step-by-step explanation:

Given that the circle has diameter 11 feet, then the radius of the circle is

The area of the circle is found using

When we substitute the radius we obtain:

Since three-quarters of the circle is shaded, the area of the shaded region can be found by multiplying the area of the whole circle by three-fourths as in A = three-fourths (pi times r squared).
