Find the Area of the figure below, composed of a rectangle and a semicircle.

Mamont248 [21]

Answer:

68.1 units²

Step-by-step explanation:

Start by finding the area of the rectangle...

$Area=lw\\Area=6*9\\Area=54$

Then, find the area of the semicircle...

$Radius=\frac{1}{2}*Diameter=\frac{1}{2}*6=3$

$Area=\frac{1}{2}\pi r^2\\Area=\frac{1}{2}\pi 3^2\\Area=\frac{1}{2}\pi 9\\Area=\frac{9}{2}\ pi\\Area\approx14.1$

Now, add the two to get...

54+14.1=68.1

Find the length of the prism if the width is 12 feet, the height is 18 feet, and the volume of the prism is 3240 cubic feet.

olga55 [171]

Known :

w = 12 feet

h = 18 feet

V = 3.240 feet³

Asked :

l = ...?

Answer :

V = l × w × h

3240 = l × 12 × 18

3240 = 216 l

l = 3240 ÷ 216

l = 15 feet

So, the length is 15 feet

Hope it helps and is useful :)
