Question

A circular pillar candle is 2.8 inches wide & 6 inches tall. What are the lateral area & surface area of the candle?

Answer 1

the formula for lateral surface area is \[\pi d h\]
does that help?

Answer 2

d = diameter = wide
h = height = tall

Answer 3

so its the same for the surface area too?

Answer 4

nope

Answer 5

surface area is \[2\pi r^2 + \pi d h\]
r is radius

Answer 6

so i would get 52.8 and 58.9

Answer 7

is that what the calculator said?

Answer 8

Answer 9
