Can someone please help me with the 2 questions below. (they go together)
il63 [147K]

Answer:

r=√(A/π)

r=2.8

Step-by-step explanation:

We want to get (r) alone on one side

A=πr^2

divide each side by π

A/π=r^2

square root each side

√(A/π)=r

r=√(A/π) is the answer to your first question.

now we are given A

r=√((25)/3.14)

put the left side into a calculator

r=2.8216632

round to nearest tenth of a centimeter

r=2.8
