The diameter below shows a circle placed inside a square. The square has an area of 132.25 ft 2. What is the approximate area of the circle?

Sagot :

Answer:

104ft^2

Step-by-step explanation:

Area of a square = L²

L is the side length of the square

132.25 ft² = L²

L = √132.25

L = 11.5ft

This shoes that the diameter of the circle is 11.5ft

Area of a circle = πd²/4

Area of a circle = 3.14(11.5)²/4

Area of a circle = 3.14(132.25)/4

Area of a circle = 103.82

Hence the approximate area of the circle is 104ft^2
