Question

Find the circumference and the area of a circle with radius 3 ft.
Use the value 3.14 for it, and do not round your answers. Be sure to include the correct units in your answers

Answer 1

Circumference = 2 x radius x Pi

= 2 x 3 x 3.14

= 6 x 3.14

= 18.84 feet

Area = pi x r ^2

= 3.14 x 3^2

= 3.14 x 9

= 28.26 square feet

Answer 2

The circumference of the circle will be C= 18.84 ft and the area of the circle will be $A=28.27 ft^2$

What is area of the circle?

The area of the circle is defined as the quantity of the space covered by the circle in a two-dimensional plane.

It is given in the question ;

Radius of the circle = 3 ft.

The area of the circle is given by the formula;

$A=\pi r^2$

$A=\pi \times 3\times 3$

$A= 28.27\ Ft ^2$

Circumference of the circle is given by

$C=2\pi r$

$C=2\pi\times 3$

$C=18.84\ Ft$

Hence the circumference of the circle will be C= 18.84 ft and the area of the circle will be $A=28.27 ft^2$
