What is the volume, in cubic centimeters, of a cylinder with a height of 12 centimeters and a base radius of 6 centimeters, to the nearest tenths place?

Please help :(

Answers

Answer:

1357.2

Step-by-step explanation:

volume = r^2 * pi * h

= 6^2 * pi * 12

=432pi

The volume of cylinder is 1357.17 cubic centimeter.

Formula to find the volume of cylinder:

V = base area × height

[tex]V=\pi \times r^{2} \times h[/tex], where r is the radius of circular base and h is the height of the cylinder.

For given example:

a base radius (r) = 6 cm,

a height of a cylinder (h) = 12 cm

Using the formula of volume of a cylinder,

[tex]V=\pi \times 6^{2} \times 12[/tex]

[tex]V=1357.17[/tex] cubic cm

Hence, the volume of a cylinder is 1357.17 cubic centimeter.

Area =  πr²

To find the Radius R we need Diameter which 290 fee so:

R = Diameter / 2

R = 290/2

R = 145 ft

Now put values in Area Formula

Area = 3.14 x (145)^2

A = 66018.5 sq feet

Alright so assuming the this is a right angle, to find the area of a triangle you have to multiply LxW and divide by 2. 3x4=12/2=6. There are 2 triangles, so 6x2=12

And then to find the area of the rectangle on the bottom, 10x4=40

Next you find the area of the rectangle on the side: 3x10=30

And finally the one that’s slanted on the top: 5x10=50

Add them up and 12+40+30+50= 132

Hiroki's goal is to collect $40 for a school fundraiser. He already collected $26.50. Hiroki wants to know how much more money he needs to collect.
Let m be the amount of money Hiroki still needs to collect. Describe the situation with an equation.

Answers

40-26.50= 13.50
You subtract 26.50 from 40 which will give 13.50

Hiroki needs to collect $13.50 more.

What is Algebra?

Algebra, a discipline of mathematics where abstract symbols rather than concrete numbers are subjected to arithmetic operations and formal transformations. The idea that there is such a separate branch of mathematics, as well as the term algebra to identify it, came about gradually through time. It tries to find solutions to equations that contain one or more unknown quantities. Although early mathematicians would not have been familiar with such a concept, the word "equation" is frequently employed to conveniently represent these operations when discussing the early history of algebra.

As per the given data:

Total amount to be collected = $40

Amount already collected = $26.50

To find the amount of money still to be collected (m):

Total amount to be collected - Amount already collected

= $40 - $26.50

= $13.50

Hence, Hiroki needs to collect $13.50 more.
