what is the area of a circle with a radius of 12 feet? estimate the area of to the hundredths place

Using 3.4 for pie

3 answers

To find the area of a circle, we use the formula A = πr^2, where A is the area and r is the radius.

Given that the radius is 12 feet and using 3.4 for π, we can calculate the area as follows:

A = 3.4 * (12)^2
A = 3.4 * 144
A = 489.6 square feet

Therefore, the area of a circle with a radius of 12 feet (using 3.4 for π) is approximately 489.6 square feet.
The answers are A 452.2, B 113.04, C 75.4, D 452.16. pick one of them
Using the formula A = πr^2, with a radius of 12 feet and 3.4 for π, we get:

A = 3.4 * (12)^2
A = 3.4 * 144
A = 489.6

Rounded to the nearest hundredth, the answer is 489.60, closest to D) 452.16.
