Answer:
34072.3 in³
Step-by-step explanation:
Step 1
The circumference of its base is 125.6 inches.
C= pi x diameter
Find the radius of the base
C/ π = Diameter
Diameter = 125.6 in/2
= 62.8 in
Step 2
The height of the cone is 33 inches.
Radius = Diameter/2
Radius = 62.8 in/2
= 31.4 in
Volume of a cone: V = (1/3)πr²h
= 1/3 × π × (31.4)² × 33
= 34072.33162 in³
Approximately = 34072.3 in³
Therefore, the volume of Nuala's cone is 34072.3 in³.

Answer:
5. Nathan will not spend enough to use the coupon. His purchase will cost $89.27
6. Ana bought 1 pair of sunglasses, 1 t-shirt, and 1 towel.
7. Austin should get $34.50 back
Step-by-step explanation:
<u>Nathan</u>
Cost of Board shorts x Number of pairs bought = Cost of Board shorts
Cost of towel x Number of towels bough = Cost of towels
Total (Board shorts) + Total (Towels) = Final price total
25.99 X 3 = 77.97
5.65 X 2 = 11.30
77.97+11.30 = 89.27
<u>Ana</u>
$33.90-$15.50-$12.75=$5.65
<u>Austin</u>
2 shirts = 12.75+12.75 (12.75 X 2) = 25.50
60.00 - 25.50 = 34.50
