(A)
Step-by-step explanation:
1/2=x/6
2x=6
x=3
THerefore, (A)
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>
