Question

The surface area of the figure below is 50.80m^2 True or False

Answer 1

For this case we have that by definition, the surface area of a cone is given by:

$SA = \pi * r * s + \pi * r ^ 2$

Where:

A: It's the radio

s: It's the slant

Substituting according to the data we have:

$SA = \pi * 2.1 * 5.6 + \pi * (2.1) ^ 2\\SA = 36.9264 + 13.8474\\SA = 50.7738 \ m ^ 2$

If we round:

$SA = 50.8 \ m ^ 2$

Answer:

True
