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).
