A cylinder has a radius of 40 ft and a height of 17 ft. What is the exact surface area of the cylinder?

Answers

Answer 1

Answer: 2 pi r h+2 pi r squared

2 x pi x 40 x 17 = 4272.566009

2 x pi x 40 squared = 10053.09649

so 4272.566009 + 10053.09649 = 14325.6625

Answers

Answer:

The value of the expression is 100

Step-by-step explanation:

we have

5,200-[40%(300*42.5)]

we know that

(300*42.5)=3*100*42.5=3*4,250=12,750

40%=40/100=0.40

substitute

5,200-[0.40*12,750]

5,200-5,100=100
