How can i find the volume of a cylinder which diameter is 10cm, and whose height is 12cm, and find the cross section?

Volume=943 cm^3 Cross section area=79 cm^2

Step-by-step explanation:

volume of a cylinder is

so 10/2=5 5^2=25*12=300*pi is about 942.477 or 943 cm^3

to find the area of the cross section, on just needs to find the area of the face of the cylinder. so pi times 5^2=pi times 25=78.540 or 79 cm^2

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
