Answer:
150.72
Step-by-step explanation:
To find the surface area, use the provided formula and the values r = 2 and h = 10. The radius of the object is 2 since it is half the distance across the circle which measures 4 inches across through the center.
SA = 2πr² + 2πrh
SA = 2π2² + 2π(2)(10)
SA = 2π*4 + 2π(20)
SA = 8π + 40π
SA = 48π
SA = 48(3.14)
SA = 150.72
Answer:
The correct option is;
B. Use a formula
Step-by-step explanation:
Given that Jim and Lillian have the dimensions of the wall they want to paint, therefore, in order to know how much paint they need to buy, they should proceed as follows;
1) Determine the quantity of paint required to paint a unit area of the wall, and record the quantity UA
2) Calculate the area, A, of the wall they want to paint, which is 15 ft. × 9 ft. = 135 ft.²
3) The amount of paint needed, AmP is therefore given by the following formula
AmP = A × AU = 135 × AU
