What is the volume of a cylinder with base radius
4 and height 7?

V = 112pi or approximately 351.68

Step-by-step explanation:

The volume of a cylinder is given by

V = pi *r^2 * h where r is the radius and h is the height

V = pi * 4^2 *7

V = pi * 16*7

V =112 pi

We can approximate pi by 3.14

V =112(3.14)

V =351.68

goog may be able to you find that answer

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
