84 + 48 = 132
132 divided by 4 = 33
Misty will need 33 pages if she puts 4 photos on each page.
Answer:
18
Step-by-step explanation:
The formula for the volume of a cylinder is:
area of cross-section x the height.
First lets work out the area of the cross-section. Since the cross-section is a circle, we use the formula π x r²
Halve the the diameter to get the radius, so we can use the formula:
30 / 2 =15
Area of cross-section
π x 15² = 706.8583471 inches²
Now that we know the area of the cross-section, we multiply this by the height to get the volume.
706.8583471 x 36 = 25446.90049
= 25446.90 (2dp)
So the volume of the cylindrical fish tank is <u> </u><u>25446.90</u>
Answer:
3x sqrt(2x)
Step-by-step explanation:
sqrt(6x^2) * sqrt(3x)
We know that sqrt(a) sqrt(b) = sqrt(ab)
sqrt(6x^2*3x)
sqrt(18x^3)
sqrt(9*2 x^2 x)
sqrt(a) sqrt(b) = sqrt(ab)
sqrt(9) sqrt(x^2) sqrt(2x)
3x sqrt(2x)
