(11+21)-(3-101)=(11+21-3-10=(11-3)+(21-101=8-18=53
Answer:
D.
Step-by-step explanation:
I don't actually know I'm guessing.
2x - 24 = x - 2
2x - x = -2 + 24
x = 22
BC = x = 22
The surface area of a cylinder that the radius tripled and it height is brought down to half is 3890.46 inches²
<h3 /><h3>How to find the surface area of a cylinder?</h3>
Surface area of a cylinder = 2πr(r + h)
Therefore,
radius is tripled = 3(7) = 21 inches
height is shrunk half its size = 17 / 2 = 8.5 inches
Therefore,
surface area = 2 × 3.14 × 21 (21 + 8.5)
surface area = 131.88(29.5)
surface area = 3890.46 inches²
