SashulF [63]
The goat is tied in the four corners of an 8-foot by 4-foot pump house. The rope is 8 feet. The goat is eating the grass, forming a circle The pattern is 3/4 of a circle radius 8 and 1/4 of a circle radius 4.

Getting the area of radius of 8 feet
Area = pi * r^2
Area = pi * 8^2
Area = 201.06 feet^2

Getting the area of radius of 4 feet
Area = pi * r^2
Area = pi * 4^2
<span>Area = 50.27 feet^2
</span>
3/4 of 201.06 = 150.80 feet ^2
1/4 of 50.27 = 12.60 feet^2

So the total area is 153.40 feet^2

Firlakuza [10]

You do not have enough money to pay your sister back and the amount left is $29

<h3>A. Do you have enough money to pay your sister back? </h3>

The given parameters are:

Amount borrowed = $130

Earnings = $12 per hour for 4 hours

Earnings = $12 per hour for 6 hours

Tip = $5

The total earnings is

Total = 12 * 4 + 12 * 4 + 5

Evaluate

Total = $101

101 is less than 130

Hence, you do not have enough money to pay your sister back

<h3>How much money left</h3>

The amount left is calculated as:

Amount left = $130 - $101

Evaluate

Amount left = $29

Hence, the amount left is $29
