Acircular cardboard piece is needed for the base of a volcano model. the volcano is 46 centimeters tall and has a volume of 800 cubic centimeters. which equation can be used to find the area of the circular base?

The equation for the volume and area of a cylinder is best for modeling this case

V=πr²h

A=2πr

Step-by-step explanation:

Given

H= The height of the volcano 46cm

V= volume of volcano 800cm³

Volume of a cylinder is given as

V=πr²h

Substituting we have

800=3.142*r²*46

800=144.532r²

800/144.532=r²

r²=5.54

r= √5.54

r=2.35cm

We can use this radius to solve for the area

Area of circular base is given as

A=2πr

Substituting we have

A=2*3.142*2.35

A=14.78cm²

the answer to this question is yes

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
