10. The compass length (3 inches) represents the radius of the circle that is about to be drawn.
We know an equation for the area of a circle is pi x r^2
So lets use that equation
A (circle) = pi x 3^2 = pi x 9 = 28.3 square inches
and 11 is one fourth
144 miles on 4.5 gallons
Solution: 144mi 4.5 32mi
------------ divided by = -------------

Answer: $21, 600
Step-by-step explanation:
Given:
Original cost (when the shop owner brought it) = $20,000
Profit amount = 20% of original cost
Discount rate = 10%
Solve:
First Step: Find the market price (before discount)
- $20, 000 × (1 + 20%) = $24, 000
Second Step: Find the discount price
- $24, 000 × (1 - 10%) = $21, 600
Hope this helps!! :)

<u>Answer:</u>
<h2>SA = 157 in²</h2>
<u>Steps:</u>
SA = 2LW + 2WH + 2LH
SA = 2(9×2) + 2(2×11/2) + 2(9×11/2)
SA = 2×18 + 2×22/2 + 2×99/2
SA = 36 + 22 + 99
SA = 157 in²
