So the selected answer would be 2√20 because that comes out to about 8.94
And 4√5 comes out to 8.94 as well but I could be wrong but yeah that's what I think
Answer:
False
Step-by-step explanation:
SA=2πrh+2πr²
SA = 2 · (3.14) · 3.6 · 9.7 + 2 · (3.14) · 3.6²
SA = 6.28 · 34.92 + 6.28 · 12.96
SA = 219.30 + 81.39
SA = 300.69
I'll show you how I do it,hope you'll like it.
5:7, 5+7=12
5/12×48 =20
7/12×48=28
answer=
5:7
= 20:28
hope it helps.....
F(-3) = (-3)^2 - (-3) = 9 - (-3) = 9 + 3 = 12
