HELP! 12. Write a formula to estimate the amount of material required to cover Firm 1’s structure, not including the floor. Explain your reasoning.

** radius = 35, height = 60**
**the shape is a cylinder**

13. Use the formula from question 12 to estimate the amount of material required to cover Firm 1’s structure, not including the floor. Show your calculations.

12. The formula to estimate the amount of material required to cover firm 1's structure not including the floor is π·r² + π·r·h

13. 10445.8 unit²

Step-by-step explanation:

12. The given parameters are;

The shape of the firm 1's structure = Cylindrical shape

The radius of the firm 1's structure = 35

Height of firm 1 structure = 60

The amount of material to cover the firm 1 structure not including the floor = The surface area of a cylinder excluding the base

The formula for the surface area of a cylinder = 2·π·r² + π·r·h

Removing the area of the base, we have

The surface area of a cylinder excluding the case  = 2·π·r² + π·r·h - π·r² = π·r² + π·r·h

The formula to estimate the amount of material required to cover firm 1's structure not including the floor = π·r² + π·r·h

13.

The amount of material to cover firm 1's structure not including the floor = π × 35² + π × 35 × 60 = 10445.8 unit².

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's
