Question

Find the total surface area

Answer 1

To find the surface area of a right cone:

  ⇒ must know the formula = $\pi rs+\pi r^2$

• s: slant height
• r: length of radius of the ciruclar base

    (look at the diagram I attached for a better explanation)

Let's look at the information given:

• r: radius length: 6ft
• s: slant height: 10

Let's solve:

 $Surface-Area=\pi *6*10+\pi* 6^2=60\pi +36\pi =96\pi = 301.592ft^2$

Thus the surface area of the shape given is 301.59 square feet

Answer: 301.59 square feet

Hope that helps!
