Can someone plz help me

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

A circle with diameter 11 feet. Three-quarters of the circle is shaded.
The radius is 5.5 feet.
The area of the whole circle is A = (5.5) squared pi.
The area of the whole circle is A = (11) 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).
The area of the shaded region can be found by multiplying the area of the whole circle by two-thirds as in A = two-thirds (pi times r squared).

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


(diameter)/(2) = 5.5feet

The area of the circle is found using


A=\pi {r}^(2)

When we substitute the radius we obtain:


A=5.5 ^(2) \pi

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).
