Answer:
200
Step-by-step explanation:
300/15
divide cost by number bought
20
you will get this number, so for 1 ball you will pay 20
20 x 10
you will take the price for one ball and multiply it by the number of balls you want to buy
200
you will have to pay this number for 10 balls
Answer:
5.5
Step-by-step explanation:
The volume of a sphere is represented by the formula 4/3πr^3. So, if we set 4/3πr^3 equal to 2048/3, we can start solving. Start by multiplying both sides by 3/4, the reciprocal of 4/3 to get rid of the fraction. This gives us πr^3 = 512. Divide 512 by π to get 163.1 (when rounded to the nearest tenth). This leaves us with r^3 = 163.1; find the cubic root of 163.1, which is 5.5, to get r
