Answer:
The 1st one is 540π
The 2nd one is 1696.46
Step-by-step explanation:
To find the volume of a cylinder, you do the following:
Where r represents the radius of the circle and h represents the height. Because it's multiplication, we can change it to:
So since the radius is 6, 6^2 is 36. Then we multiply by 15, to get 540. Then now since we don't need to multiply the pi, you just leave it as 540π.
For the second one, multiply 540 by pi to get the answer, then round it to the nearest hudredth to get 1696.46.
Answer:
$ 2.30
Step-by-step explanation:
Given that the sales tax rate
The cost of the book is $ 12.99.
So, the tax on the book= 8.5% of 12.99
=1.10
So, the sales tax on the book is $ 1.10.
The cost of the video game is $ 39.99.
So, the tax on the book= 8.5% of 39.99
=3.30
So, the sales tax on the book is $ 3.40.
The difference of taxes on both the items = $ 3.40-$ 1.10=$ 2.30
So, the tax on the video game is $ 2.30 more than then tax on the book.
