Answer:
33 pi square units
Step-by-step explanation:
First find the area of the entire circle. It is A = πr² = π(6)^2 = 36 pi square units.
Then form the fractional multiplier
11/6 π
----------- = 11/12
2 π
... and multiply the previous result (area of the whole circle) by this 11/12:
Area of the sector is then A = (11/12)(36 pi square units), or 33 pi square units
Answer:
option "D"
Step-by-step explanation:
Answer:
- length: 75 ft
- width: 72 ft
Step-by-step explanation:
Length: (25 yd)(3 ft/yd) = 75 ft.
Width: (8 lanes)(3 yd/lane)(3 ft/yd) = 72 ft.
The length and width are 75 ft and 72 ft, respectively.
Answer:
0.6 hours
Step-by-step explanation:
Let's say the swimming pool is 12,000 gallons.
The flow rate of the cold water pipe is:
12000 gal / 4 hr = 3000 gal/hr
The flow rate of the hot water pipe is:
12000 gal / 6 hr = 2000 gal/hr
If the cold water pipe is turned on for three hours, the volume of water is:
3000 gal/hr × 3 hr = 9000 gal
That leaves 3000 gallons. The time to fill the rest of the pool with both the cold and hot water pipes is:
3000 gal / (3000 gal/hr + 2000 gal/hr) = 0.6 hr
It takes 0.6 hours (36 minutes).
