ANSWER QUICK The area of each triangular base is: A = 1/2(b)(h)

A = 1/2(3)(4)

A= A?

There are two bases, so total base area is

The lateral area is

A = (12)(3) + 12(5) + 12(4)

A= f

The total surface area is ft?

ft?

5 ft

4 ft

12 ft

3 ft

7

step-by-step explanation:

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d

question

given the diagram below, what is md?

the sum of the interior angles is 360°

take away from 360 the sum of the knows angles and you will have the angle d.

360 - 108 - 108 - 72 = 72°
