What will be the balance in an account that was initially $400 and has been drawing 5.5% interest compounded continuously for 8 years?

$613.87

Step-by-step explanation:

First, fortunately for us, there is a formula to calculate the compound interest. It is A=P(1+)^nt

where A is the amount you will have

P is the principal, or starting, amount

r is the interest rate (decimal)

n is the number of times the amount is compounded per year

t is the time, in years

So, plugging your values into the equation gives us

A=400(1+)^1*8

Simplifying gives us A=613.87

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
