Given:
Inner cone: diameter = 12 cm ; height = 6 cm
Outer layer: diameter = 12 cm ; height = 15 cm

Volume of a cone = π r² h/3

Inner cone: V = 3.14 * (6cm)² * 6cm/3 = 3.14 * 36cm² * 2cm = 226.08 cm³
Outer layer: V = 3.14 * (6cm)² * 15cm/3 = 3.14 * 36cm² * 5cm = 565.20 cm³

Volume of Outer layer :         565.20 cm³
less: Volume of inner layer:<u> 226.08 cm³</u>
Volume of cream filling:        339.12 cm³

The width of a rectangular swimming pool is 12 meters less than the length, and the perimeter is 72 meters. Find its dimensions
Elis [28]

Answer:

The dimensions are 24 and 12 meters.

Step-by-step explanation:

W + L + W + L = 72   perimeter

(L-12) + L + (L-12) + L = 72

4L - 24 = 72

4L = 72 + 24 = 96  ====>  L = 96%2F4 = 24.

For the following figure, complete the statement for the specified points.
AVprozaik [17]

The correct answer is coplanar


EXPLANATION


Coplanar means the three points A , B and Q are on the same plane.


They are not colinear, because they are not in a straight line. It is only A and Q that are on the same straight line. If B had fallen in line with them, the three points would have been collinear as well.
