If the radius of a circle is 3.5 inches, its diameter is inches and its approximate area is square inches

diameter is radius x 2

3.5 x 2 = 7 inches

Area = PI x r^2

using 3.14 for PI

area = 3.14 x 3.5^2 = 3.14 x 12.25 = 38.465 square inches round answer as needed

 The diameter of circle is 7 inches and its approximate area is 38.5 square inches.

Step-by-step explanation:

Given : The radius of a circle is 3.5 inches.

Diameter of circle is double the radius.

i.e. Diameter of circle will be 2(3.5)=7 inches.

We know that the area of a circle is given by :-

, where r is the radius of the circle.

Substitute r=3.5 in the formula, we get

Hence, the diameter of circle is 7 inches and its approximate area is 38.5 square inches.
