Answer:
The answer is units squared.
Step-by-step explanation:
If we find the diameter, we can find the radius by halving the diameter.
We can find the diameter by using the endpoints of the diameter.
The distance formula will give us the length between (3,1) and (9,9).
The distance formula is .
The distance between the 's is 9-3=6.
The distance between the 's is 9-1=8.
The distance between the points is given by .
The radius is therefore .
We are asked to find the area of this circle.
The formula for finding the area of a circle is .
Since the radius is , then the area in terms of
,(pi), is
.
The answer is units squared.
Answer
Find out the what was his total cost .
To prove
As given
A tent was marked up 150% from an original cost of $52.
Last Friday, Ethan bought the tent and paid an additional 10% in sales tax.
Than the equation becomes
150 % is written in the decimal form .
= 1.5
10 % is written in the decimal form .
= 0.1
cost of the tent when 150% marked up from origianl price = 1.5× 52
= $ 78
cost of the tent = origianl cost + 150% marked up from origianl price
= $52 + $78
= $ 130
Sales price on the tent = $130 × 0.1
= 13
Total cost of the tent = $130 + $13
= $143
Therefore the cost of the tent is $143.
