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

Answers

Answer:

The area: 28.26m^2, the circumference: 18.85m

Step-by-step explanation:

The area of a circle is 3.14(3)^2, which is 28.26, the circumference is 2(3.14)(3)=18.85m.

Answer:

Area of a circle= π[tex]r^{2}[/tex]

3.14 x [tex]3^{2}[/tex] = 18.84

The area of the circle is 18.84 [tex]m^{2}[/tex]

Circumference of a circle = 2πr

2 x 3.14 x 3 = 18.84

The circumference of the circle is 18.84 m

They are both the same number but the area is squared.
