Area of a circle is found using the formula: A = PI x r^2 where r is the radius of the circle, which is half the diameter.
Using the information in the problem you have:
A= PI x 15^2
A = PI x 225
A = 706.5 sq. In.
Answer:
A =706.5 in^2
Step-by-step explanation:
The area of a circle is given by
A = pi r^2 where r is the radius
We are given the diameter
r = d/2 = 30/2 = 15
A = pi * 15^2
A = pi*225
We can approximate pi by 3.14
A = (3.14)*225
