What is the volume of a cylinder that has a radius of 4 cm and a length of 8cm

volume of a cylinder = 401.92cm³

Step-by-step explanation:

to calculate the volume of a cylinder , we will use the formular for finding the volume of a cylinder

volume of a cylinder =  πr²h

given that

height of the cylinder = 8cm

radius of the cylinder = 4cm

volume of a cylinder = π × (4cm)² × 8cm

volume of a cylinder = π × 16cm² × 8cm

volume of a cylinder = π128cm³

value of π = 3.14

volume of a cylinder = 3.14 × 128cm³

volume of a cylinder = 401.92cm³

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.

you have to put the graph on here with the question
