Question

Instructions: Find the surface area of the figure below. Round your answers to the nearest tenth, if necessary.

Answer 1

The surface area of the figure given is of: 61.3 yd².

What is the combined surface area of a figure?

The combined surface area of a figure is the area of each figure.

This figure is composed by:

• A circle of radius 3 yd.

• A triangle with base 6 yd and one leg 11.4 yd.

The area of the circle is given as follows:

$A = \pi r^2 = \pi \times 3^2 = 9\pi$

For the triangle, we need to find it's height, which is the leg of a right triangle, in which one of the sides is 3 and the hypotenuse is 11.4, hence:

h² + 3² = 11.4²

$h = \sqrt{11.4^2 - 3^2}$

h = 11 yd.

Hence the area of the triangle is:

A = 0.5 x 6 x 11 = 33 yd²

The surface area of the figure is:

9pi + 33 yd² = 61.3 yd².
