Micah has a new remotely controlled car that has a circular range with a radius of 30 feet. What is the area of the circular range?

Answer 1

A = pi * r^2

I'll be glad to check your answer.

Answer 2

"I'll be glad to check your answer." What do you mean about that?

Answer 3

What does the r^2 stand for?

Answer 4

"You have to figure it out then she says if your right or not. She can't just give you the answer." Oh okay i understand

Answer 5

r^2 is radius squared

Answer 6

So do i multiply 30 by 2?

Answer 7

No.
The radius is half of the diameter. So this radius is 15.

15^2 = 15 * 15

A = 3.14 * 15^2

A = ?

Answer 8

oh so i do half of 15 then multiply 3.14

Answer 9

Nope. Read what I posted again -- and again if necessary.

Answer 10

oh ok

Answer 11

so the answer is 47.1 right

Answer 12

No.

What is

15^2 = 15 * 15 = ?

Answer 13

Actually, the radius is 30 ft , not 15

so area = π(30)^2 square feet = .....

Answer 14

oops! Thanks for catching that Reiny.
