Question

A particular model of walkie-talkie can broadcast in a circular area. The radius of the broadcast area is 10,000 feet. Find the area of this circle to the nearest square foot. Use 3.14 for p.

Answer 1

The right answer to this question is 314,000,000 square feet

Answer 2

The area of the circle is found by multiplying the square of the radius and pi = 3.14.

`A = 3.14 ( r^(2) ) \\ A = 3.14(10,000ft )^(2) A=314,000,000 ft ^(2)`
The right answer to this question is 314,000,000 square feet.
