Answer:
a) 50.24 ft²
b) 150.72 ft²
Step-by-step explanation:
Jason is painting a large circle on one wall of his new apartment. The largest distance across the circle will be 8 feet.
The distance across a circle is also called a diameter, Hence,
D = Diameter = 8 ft
The Area of a circle = πr²
r = Diameter/2 = 8ft/2 = 4ft
π = 3.14
Hence,
The Area of the circle = π × (4 ft)²
= 50.24 ft²
a) Approximately the amount of wall the circle will cover is 50.24 ft².
b) How much area will he cover if he painted a circle on three walls?
This is calculated as:
1 wall = 50.24 ft²
3 walls = x
Cross Multiply
x = 3 × 50.24 ft²
x = 150.72 ft²
It is already in radical form......... but, if you want us to make it into exponential form, it is 8x^(2/3)

Answer = 1/2
- I’m pretty sure that is it... hope this works for ya!!
Answer:
10
Step-by-step explanation:
you derive the answer by taking the total length of the pipe (7 1/2 foot), divided by the length of each piece (3/4 foot).
7 1/2 ÷ 3/4 = <u><em>10</em></u>
