Find the volume of soup can if the diameter is 6.5 in and the height is 9 in

Answers

Answer 1

Answer:

Answer:

V =298.49625 in^3

Step-by-step explanation:

Volume of a cylinder is given by

V = pi * r^2 *h

We know the diameter so we can find the radius

r = d/2 =6.5/2 = 3.25

and we know the height =9

V = pi * (3.25)^2 *9

V = pi*95.0625

If we approximate by 3.14

V = 3.14*95.0625

V =298.49625 in^3

Answer 2

Answer:

Answer:

$V = 95.0625\pi$ inches

Step-by-step explanation:

The soup can is a cylinder, and since the diameter is 6.5 inches then the radius is 3.25 inches. The formula for the volume of a cylinder is $V = \pi r^(2)h$ , and by plugging in the values we have, we get $V = \pi *3.25^(2) *9$ .

Solving this equation gives us $V = 95.0625\pi$ inches.

patrick read 20 pages of his book in 4 hours . Todd read 25 pages in 5 hours. Did both at the same rate?

Answers

All you need to do is find the rate that each boy read and compare them.

Patrick
20 pages/4 hours
=5 pages/hour

Todd
25 pages/5 hours
=5 pages/hour

Yes both boys read at the same rate (5 pages/hour)

Solve:-

Patrick:-
20 pgs = 4 hrs

Todd:-
25 pgs = 5 hrs

Divide:-

Patrick:-

20 ÷ 4 = 5
5 pgs per hr

Todd:-

25 ÷ 5 = 5
5 pgs oer hr

Yes, Both boys read at the same rate, 5 pgs per hr

You've been given a scholarship of $10,000. If you invent it at a 3.4% annual interest rate, how much interest will you have earned a year's time?

Answers

You can do this by multiplying 10000 by 103.4 percent
10,000 times 100 percent is 10,000 so 10,000 times 103.4 percent is the extra 3.4 percent

mary made a small pan of ziti and a small pan of lasagna. she cut the ziti into 8 equal parts and the lasagna into 9 equal parts. her family ate 2/3 of the lasagna. if her family ate more lasagna than ziti what fraction of the ziti could have been eaten?

Answers

Answer:

Hence, the possible fractions would be:

$(1)/(8),(2)/(8),(3)/(8),(4)/(8),(5)/(8)$

Step-by-step explanation:

" Mary made a small pan of ziti and a small pan of lasagna. she cut the ziti into 8 equal parts and the lasagna into 9 equal parts" .

Now her family ate 2/3 of the lasagna.

That means her family ate 6 lasanga. ( Since 2/3 of 9 parts is 6{ as (2\3)×9=6} ).

Now it is given that her family ate more lasagna than ziti.

i.e. her family would have eaten less than 6 ziti's.

I.e. they would have eaten either 1,2,3,4 or 5 ziti's.

Hence, the possible fractions would be:

$(1)/(8),(2)/(8),(3)/(8),(4)/(8),(5)/(8)$

Well, 2/3 times 9 is 6 parts of lasagna, so that means that the family must have eaten less than 6 piece of ziti; and 1/4 times 8 equals 2 parts of ziti...so 1/4 can be your answer!
