tina wants to save money for school. tina invests $800 in an account that pays an interest rate of 7.5%. How many years will it take for the account to reach $14,000? round your answer to the nearest hundredth.

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

the answer is two. hope this !

i think it might be a but you might want a second opinion
