Question

A porch has the shape of a quarter circle with a diameter of 5 ft.

What is the approximate area of the porch, rounded to the nearest square foot? Use 3.14 to approximate for pi .

Answer 1

I got done with this one. Can you help me with another @iGreen

Answer 2

Act like it's a whole circle, find the area, then divide by 4.

A = pi * r^2

A = 3.14 * 2.5^2

Multiply 3.14 * 2.5 * 2.5

Answer 3

Which figures can be used to find the area of the composite figure?

Choose exactly two answers that are correct.



A.
a rectangle with an area of 34 cm2

B.
a rectangle with an area of 72 cm2

C.
a quarter circle with an area of cm2

D.
a quarter circle with an area of cm2
