Find the future value of an account if $7, 800 is deposited at 5.5 % interest compounded weekly and the money is left for 7 years. Round answer to 2 decimal places

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.
