The area of a circular plate is 625pi sqaure in. If the radius of the plate is tripled what is the new area

5625in²

Step-by-step explanation:

Area of the plate = πr²

625π = πr²

625 = r²

r = √625

r = 25in

If the radius of the plate is tripled, then the new radius will be 3(25) = 75in

New Area = π(75)²

New Area = 5625π in²

If the radius is tripled, the new area of the plate is 5625in²

is this a multiple choice question?

if so it's a and c

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice
