Question

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

Answer 1

When solving area, you do length multiplied by width. Then, you'll get your answer. Hope that helped! :)

Step-by-step explanation: Length times width is the main key when solving area. If you know how to multiply both of those, you can get your answer.

Answer 2

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).

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).
