Question

Which is the correct first step in finding the area of the base of a cylinder with a volume of 26x cubic meters and a height of 6.5 meters?

v=bh 6.5=b(26x)

v=bh v=26pi+(6.5)

v=bh v=26pi(6.5)

v=bh 26pi=b(6.5)

Answer 1

`\large\boxed{V=Bh,\ 26x=B(6.5)\to B=4x}`

Explanation:

`\text{The formula of a volume of cylinder:}\\\\V=Bh\\\\\text{We have}\ V=26x\ m^3\ \text{and}\ h=6.5\ m.\\\\\text{Substitute:}\\\\26x=B(6.5)\qquad\text{divide both sides by 6.5}\\\\(26x)/(6.5)=B\to B=4x`
