Acone shaped funnel can hold 314 cubic inches of water. if the height of the funnel is 12 inches what is the radius of the funnel

The radius of cone shaped funnel is 5 inches

Solution:

To calculate the volume of a cone, we have to multiply the base area, in this case the area of a circle:

by its height and by

Here, volume = 314; h = 12;

we already know

On substituting the vales we get,

Bringing 3.14 to the L.H.S,

On solving we get,

On dividing 100 and 4 we get,

Taking roots on both sides,

Hence, radius = 5 inches

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
