Question

surface area of the net diagram of the right circular cylinder is 715.92 meters2, find the height. Use 3.14 for π.

Answer 1

The surface area of a right circular cylinder is given by the formula:

Surface Area = 2πrh + 2πr^2

Given that the surface area is 715.92 meters^2 and using the value of π as 3.14, we can set up the equation:

715.92 = 2(3.14)(12)h + 2(3.14)(12)^2

715.92 = 75.36h + 904.32

Subtracting 904.32 from both sides gives:

-188.4 = 75.36h

Dividing by 75.36 on both sides gives:

h ≈ -2.5

Since the height of a cylinder cannot be negative, there may be an error in the calculation. Please recheck the values provided and the calculation.
