A = pi * r^2
I'll be glad to check your answer.
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?

"I'll be glad to check your answer." What do you mean about that?
What does the r^2 stand for?
"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
r^2 is radius squared
So do i multiply 30 by 2?
No.
The radius is half of the diameter. So this radius is 15.
15^2 = 15 * 15
A = 3.14 * 15^2
A = ?
The radius is half of the diameter. So this radius is 15.
15^2 = 15 * 15
A = 3.14 * 15^2
A = ?
oh so i do half of 15 then multiply 3.14
Nope. Read what I posted again -- and again if necessary.
oh ok
so the answer is 47.1 right
No.
What is
15^2 = 15 * 15 = ?
What is
15^2 = 15 * 15 = ?
Actually, the radius is 30 ft , not 15
so area = π(30)^2 square feet = .....
so area = π(30)^2 square feet = .....
oops! Thanks for catching that Reiny.
