THIS IS AREA OF CIRCLES PLS 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

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

i think it might be a but you might want a second opinion
