Answer:

Step-by-step explanation:
Area of a circle = 
However, the question wants to use 3.14 instead of
.
Since the radius is given, which is 18 feet, we can plug and chug.

However, the question wants us to round it to the nearest tenth.
Therefore, the answer is 
Answer:
x=7
Step-by-step explanation:
Make the length x+4 and the width x and then make a formula x(x+4)=21
then u ll get x^2+4x-21=0 and then solve for x ..... the width is 3
Answer:
C
Because of the markings showing equal length lines 7x + 4 is double 4x or 48 is three times the length of 4x
Either solve 7x + 4 = 8x
4 = x
Or solve 48 = 12x
4 = x
Substitute back in to 7x + 4 ......MN = 7 x 4 + 4 = 32
