Using 3.14 as an approximation for pi, find the diameter, circumference, and area of the circle with a radius of 5 cm. Do NOT include units in your answer. Part A Diameter Part B Centimeter Part C Area

The diameter of this circle is 10, the circumference is 31.4 and the area is 58.5.

Step-by-step explanation:

The diameter of a circle is two times it radius so we have:

d = 2*r

d = 2*5 = 10

The circumference of the circle is given by the following formula:

circumference = 2*pi*r

circumference = 2*3.14*5

circumference = 10*3.14 = 31.4

The area of the circle is given by the following formula:

area = pi*r²

area = 3.14 * (5) ²

area = 3.14*25

area = 78.5

The diameter of this circle is 10, the circumference is 31.4 and the area is 58.5.
