10 hours.
If you multiply 2 1/2 by 4, the product is 10.

r^2 = cross-sectional area of paintbucket.
3.14 (Your approximate value of pi) * 9^2 = 254.34
254.34 * 9.5 = total volume of bucket.
2,416.23 in^3.
0.09$ * 2416.23 = cost
The cost would be $217.46 (To the nearest cent)
The area is 380.13.
To find the area you use the formula pi times radius squared. The radius is half the diameter, in this case 11, so therefore the area is 380.13
A=Area
A=3.14 x 10²=20
A=3.14 x 20 = 62.8
A=62.8
Answer:
(a)6.82mph
(b)22 ft/sec
Step-by-step explanation:
Eric's Speed = 10 ft/sec
The Ferry's Speed = 15 miles per hour
<u>Conversion Unit</u>
- 1 mile = 5280 feet
- 1 hour = 3600 seconds
<u>Guide</u>
- When converting from a smaller unit to a larger unit we divide
- When converting from a larger unit to a smaller unit we multiply
(a)To convert Eric's Speed 10 ft/sec to miles per hour

(b)To convert the Ferry's Speed 15 mph to ft/sec
