Answer:
C≈27 feet
Step-by-step explanation:
A=πr²
A/π=r²
√A/π =r or –√A/π=r (refused)
then r =√(A/π) =√(58/π) =4.297829403 feet
C=2πr=2π(4.297829403)=27.00405856≈27 feet
Answer:
13
Step-by-step explanation:
2(x-1)+8=4x-20
distribute 2
2x-2+8=4x-20
2x+6=4x-20
subtract 2x from both sides
6=2x-20
add 20 to both sides
26=2x
divide both sides by 2
x=13
