a cone is a solid made from a disc, a point not in the same plane as the discs and all points between them. true or flase?

False.

Step-by-step explanation:

A cone is not a solid made from a disc, a point not in the same plane as the discs and all points between them.

Mathematically, the volume of a cone is given by the formula;

Where;

V is the volume of the cone.

r is the radius of the base of the cone.

h is the height of the cone.

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
