PLEASEEE HELPPP
A cone-shaped mold is filled with cake batter. The height of the mold is 15 inches, and the base diameter is 5.5 inches. What is the volume of the mold? Round to the nearest tenth.

Sagot :

[tex]vol. \: of \: cone = \frac{1}{3} \pi \times r ^{2} \times h[/tex]

r = radius

h = height of cone

radius = 5.5÷2

= 2.75

vol. of mold = 1/3π × (2.75)^2 × 15

= 118.79 (5sf)

= 118.8 (nearest tenth)

Answer:

118.8 cubic inches

Step-by-step explanation:

volume of a cone is

[tex]vol \: = \frac{1}{3} \times \pi \times \frac{ {d}^{2} }{4} \times h[/tex]

where d is base diameter and

h is cone height.

hence

[tex]vol \: = \frac{1}{3} \times \pi \times \frac{ {5.5}^{2} }{4} \times 15 \\ = \pi \times \frac{30.25}{4} \times 5 \\ = 118.8 \: cu \: in[/tex]
