V=(pi)r(^2)h solve for r

The value of r = √{(V)/πh}

Step-by-step explanation:

Here, we are to make r the subject of the formula

V = π * r^2 * h

r^2 = V/(π * h)

To find r, we need to find the square root of both sides

r = √{(V)/πh}

Step-by-step explanation:

The equation for volume is incorrect. The volume of a cylinder with radius r and height h is πr²h.

volume = π(2b)²(5b+3)

= π(4b²)(5b+3)

= π(20b³+12b²)
