A cylinder has a base diameter of 16cm and a height of 19cm. What is its volume in cubic cm, to the nearest tenths place?

V = 3216.9

Step-by-step explanation:

Volume of a cylinder = π h

We are given diameter, 16cm, and half of it is the radius

r = 8cm

h = 19cm

Substitute the values into the equation

V = π * * 19

V = 3216.9

Step-by-step explanation:

The formula for the area of the circle is:  

To work this out you would first need to find the area of the circle. To do this you would first divide the diameter of 16 by 2. This is to work out the radius, which gives you 8. Then you would multiply pi by 8 squared. This is to work out the area of the base of the cylinder (circle), which gives you 201.06. Then you would multiply 201.06 by the height of 19, which gives you 3820.14.

1) Divide 16 by 2.

2) Multiply pi by 8 squared.

3) Multiply 201.06 by 19.

question: how many people can she serve?

answer: she can serve 16.66666667 people. so she can only give 16 people a complete serving.

question: does she have enough ice cream for her guests?

answer: no. explanation: she only has enough for 16 people to have a full serving. however, she can give a 17th person a partial serving.

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
