what is the volume of a cone with the height of 8cm and the radius of 12cm
a. 6510 cm3
b. 3260 cm3
c. 2170 cm3
d. 1206 cm3

Sagot :

[tex]V = \frac{\pi *h*r^2 }{3} = \frac{ \pi *8*12^2}{3} = \frac{1152 \pi }{3} = 384 \pi = 1206.37157898[/tex]
D. 1206 cm^3

volume=1/3 times area of base times height
area of base=area of a circle=pi times radius^2

volume=1/3 times pi times radius^2 times height

height=8
radiu=12

volume=1/3 times pi times 12^2 times 8
volume=1/3 times pi times 144 times 8
volume=1/3 times pi times 1152
volume=pi times 384
volume=384pi cm^3 cubic centimeters

aprox pi to 3.14
voolume=384 times 3.14=1205.76
closest one is d

the answer is D
