(25 points and brainliest)find the volume of a cone with a diameter of 12 m and a height of 7 m
a.336 π m³
b.84 m³
c.84 π m ³
d. 252 π m³

C

Step-by-step explanation:

cone: 1/3 * π * r^2 * h

h=7

d=12

r=6

formula: 1/3 * π * 6^2 *7

1/3*π*36*7 = 84π m^3

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

t= 1/3.

hope this .
