Question

An icicle is in the shape of an inverted cone with a diameter of 11 mm and a height of 90 mm. How much frozen water is in the icicle? Use 3.14 for Pi. Round the answer to the nearest tenth.

1,036.2 millimeters cubed
1,554.3 millimeters cubed
2,849.6 millimeters cubed
4,662.9 millimeters cubed

Answer 1

2849.6

Explanation:

Answer 2

Answer: 2,849.6 millimeters cubed

Explanation:

The volume of a cone = πr^2h/3

where π = 3.14

r = radius

h = height

To find the radius, we divide the diameter by 2. This will be:

Radius= Diameter/2 = 11/2 = 5.5mm

Height = 90mm

Volume= πr^2h/3

= (3.14 × 5.5^2 × 90)/3

= (3.14 × 30.25 × 90)/3

= 8548.65/3

= 2849.55

Rounding to the nearest tenths will be= 2,849.6 millimeters cubed
