Step-by-step explanation:

To find x,

$21x - 9 = 117$

$21x = 126$

$x = 6$

To find arc AB,

$21(6) - 9 = 117$

To find Arc AE,

$117 + x = 180$

$x = 63$

Arc ABC,

$117 + 63 = 180$

ACE

$180 + 27 + 90 = 297$

The mold for a cone has diameter of 4 inches and is 6 inches tall what is the volume of the cone mold to the nearest tenth

Nesterboy [21]

The formula for the volume of a cone is
v = ( 1 / 3) h pi r^2
where h is the height of the cone
pi is 3.1416
r is the radius of the cone

since diameter is given
D = 2r
r = D/2 = 4/2 = 2 in

substitute the given
V = (1/3) (6) (3.1416) (2^2)
V = 25.1 cubic in
