Answer:
The answer to your question is Surface area = 432 ft²
Step-by-step explanation:
Data
diameter = 16 ft
height = 8 ft
slant height = 10 ft
pi = 3
Process
1.- Write the formula to calculate the surface area
Surface area = pi x radius x slant height + pi x radius²
2.- Substitution
Surface area = (3 x 16/2 x 10) + (3 x (16/2)²)
-Simplification
Surface area = 240 + 192
-Result
Surface area = 432 ft²
5 feet is equal to 60 inches. 60 inches divided by 2.5 inches per hour means it would take 24 hours for the drill to reach five feet (assuming it maintains the same rate of digging)
26,500 - 19,610 = 6,890
6,890 would be your price discount, but now you'd have to find your percent discount. Make it into an equation to make things easier.
6,890/26,500 = p/100
(6,890*100)/26,500 = p
6,890*100 = 689,000
689,000/26,500 = 26
The price discount would be 26%.
