Question

THIS IS AREA OF CIRCLES PLS ANSWER​

Answer 1

Radius- half of diameter

Plug-in numbers:
3(5)^2=
75 ft^2

Answer 2

Answer:

75ft^2

Step-by-step explanation:

A = pi*r^2

The circle already gives the diameter and the diameter is two times the radius, so if you were to divide the diameter by two, you would get 5.

Knowing the radius is 5 and seeing how they replaced pi with 3 we can set up the equation.

3*(5)^2 = A

Simplify

3*25

Multiply

Area=75ft^2
