I need some help with this!

Step-by-step explanation:

The following formula can be used to find the volume of a sphere,

Where (r) represents the radius of the sphere or the distance from the center of the sphere to its outer edge. The term () represents the numerical constant (). In this problem, one is given that the radius of the sphere is (1). Substitute this value into the formula and simplify to solve,

3

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!
