Answer:
18550cm²
Step-by-step explanation:
140×110=15400
½×70×90=3150
15400+3150=18550
Answer:
r = sqrt( 3V/( pih))
Step-by-step explanation:
V = 1/3 pi r^2 h
Solving for r
Multiply each side by 3
3V = pi r^2h
Divide each side by pi h
3V/( pi h) = r^2
Take the square root of each side
sqrt( 3V/ (pi h) )= sqrt( r^2)
sqrt( 3V/ (pi h)) = r
Step-by-step explanation:
2x+8=2x+5
2x-2x=15-8
0x=7
The domain is "x", because that is what you input
