Ido not understand how to figure this out, every way i try doesn't even come close to any of the answers to pick from.

option-D

Step-by-step explanation:

we can use formula

where

PMI is payment amount per period

P is initial principal

i is interest rate per period

n is total number of period

we are given

APR=4.6%

age from 65 to 90

so, t=90-65=25

we know that there are 12 months in a year

so,

now, we can plug values

now, we can simplify it

So, option-D is closer one

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 !
