A cylinder has a height of 17 centimeters and a radius of 13 centimeters. What is its volume?
Use a 3.14 and round your answer the nearest hundredth.

Answers

Answer 1

Answer:

Check explanation

Step-by-step explanation:

There are two ways to solve this, I'm not sure which way is the correct one:

1. Solving with 3.14

V=πr²h

V=(3.14)(13)²(17)

V=(3.14)(169)(17)

V=(3.14)(2873)

V=9021.22

9021.22 rounded to the nearest hundredth is 9021.22

2. Solving with π (I used a calculator to solve with π)

V=πr²h

V=π(13)²(17)

V=π(169)(17)

V=π(2873)

V=9025.79569376

9025.79569376 rounded to the nearest hundredth is 9025.8

The question says to use 3.14 so it can be method 1, but the question also asks to round to the nearest hundredth and method 2 leads me to actually being able to round so it can be suspected that method 2 is the correct way. Whichever you think is best can be chosen and sorry if this isn't a clear answer! I hope it does help.

Answer 2

Answer:

V=9021.22

Step-by-step explanation:

The formula for a cylinder is πr(r)(h)

r=13

h=17

π13(13)(17)

π169(17)

π2873

π=3.14

3.14(2873)

9021.22

V=9021.22

Jim is baking cookies. He only wants to make 2/3 of a batch of cookies. The recipe calls for 7/8 of a cup of milk. How much of a cup of milk should he use? *

Answers

Answer:

1 5/16 cups

Step-by-step explanation:

If the recipe calls for 7/8 cup of milk for 1 batch of cookies, then we divide 2/3 by 7/8. 7/8 * 3/2 = 21/16 = 1 5/16 cups.

7/8 of a cup of milk divided by 2/3 of a batch. No

Answers

Answer:

12(x+ 30)

Step-by-step explanation:

360 is the down payment and 12x is the monthly payment

With regards to the function as monthly we realise there are 12 months in a year so it could equally mean (12 months x amount) or $12 dollars multiplied by x)

Factorising  We always put the highest common factor outside of the brackets when dealing with 2 numbers that can include variables such as x or 12x counting as one of the two.

12x+360

12(x+ 30)

Which is done as 12 x 30 = 360

We always try units first in numbers end in zero ie) 30 into 60 is x2 and 30 into 300 is 10 so our first highest common factor is 12 as its our largest number available from the smallest number given being 12.

So 12 is our highest common factor.

A common factor is a factor that is shared by two or more numbers. For example, a common factor of 8 and 10 is 2, as 2 is a factor of 8, and 2 is also a factor of 10. The highest common factor (HCF) is found by finding all common factors of two numbers and selecting the largest one

how many faces does this shape have?

Answers

This is a triangular pyramid and has 4 faces.

Answer:

5

Step-by-step explanation:

Faces is essentially the number of sides. In an easier shape like this you could just count the number of sides. You would have 5 faces in this shape.

On a side note, when dealing with convex polyhedrons(you might not have gotten into this) you can find the number of edges by by adding the number of vertices, plus the number of vertices, minus 2.

For example, lets take a cube. The cube has 6 faces and 8 vertices. 6 + 8 - 2 = 12 edges
