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

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x
