Answer:
489.40 cm³
Step-by-step explanation:
Since the cross section is parallel to their respective bases, hence:
Area of the cylinder cross section = area of the circular base = πr²
where r is the radius of the cylinder base.
Area of other cross section = area of rectangle base = 3.8 cm * 8.1 cm
Since both cross sections have same area, hence:
Area of cylinder cross section = Area of rectangle base
πr² = 8.1 * 3.8
r² = 9.8
r = 3.1 cm
Volume of the cylinder = πr²h = π(3.1)²(15.9) = 489.40 cm³
Divide top and bottom by any number that's fits into both of them keep doing that until it's not possible Hope that helped Have a good day! :-)
Charlie buys 2.5 pounds of oranges for 3.75.
To find out how much he will pay for 1 pound of oranges, use the proportion
2.5/3.75 = 1/x
Cross multiply to get x = $1.50 per pound of oranges.
Answer:
390 miles
Step-by-step explanation:
30 mpg means that he gets 30 miles for every gallon.
If he has 13 gallons means that you multiply 30 by 13.
30 * 13 = 390 miles
Answer:
36
Step-by-step explanation:
2 *3 sqare root 3 * 12
Solving gives:
6 sqare root 36.
sqare root 36 = 6
2 * 6 * 3
So our answer is 36.
