What is the area of this polygon?

Answers

The middle is a square with side length of 12cm

Area of the square = 12 x 12 = 144 cm^2

There are 4 triangles with base of 13cm and height of 8 cm

Area of triangle = 1/2 x base x height

Area = 1/2 x 12 x 8 = 48cm^2 each

48 x 4 = 192 cm^2

Total area = 144 + 192 = 336 cm^2

What is the area of this circle? (Express your answer using π.)
(Note: The diameter is 10ft.)

Answers

The area is πr².
The radius r is half the diameter. The diameter is 10 ft so the radius is 5 ft.

A=\pi * 5^2=25 \pi

The area is 25π ft².
Area of a circle is:

A = pi * r^2

If the diameter is 10 feet, the radius will be half of that or 5.

So:

A = 3.14 * 5^2

Simplify exponent:

A = 3.14 * 25

Multiply:

A = 78.5
