Answer:
49 pi
Step-by-step explanation:
I'll assume you want to know how big the carpet is. You need to find the area of the room, which is a circle. The area of a circle is given as pi*r^2, where r is the radius. The diameter is twice the radius, so as the problem gives us a diameter of 14, the radius would be 7. Plug in 7 for r, and we get 49pi.
93600 because 65 beats in a minute x 60 minutes every hour = 3900 beats every hour.
3900 beats every hour x 24 hours = 93600
Answer:
255.13 or 255.125
Step-by-step explanation:
2.5 times 3.14 equals 7.85
7.85 times 32.5
The volume of a cylinder is pi*height*radius^2 = pi*5*(14/2)^2 = 769.69 ft^3. To get the total gallons multiply 769.69 ft^3 by 7.5gal/ft^3 to get 5772.6765 gallons or 5773 gallons rounded to nearest whole number.
