jack knows the surface area of a cylinder and its radius. he wants to find the cylinder's height. he needs to rewrite the formula a
to find the cylinder's height (h) in terms of the cylinder's surface area (a) and its radius (1). which is the correct formula?
o a r = r + 24/1
b. h=24
oc. h= 4-2
od. h = 4 9

D) h = A/2πr - r

Step-by-step explanation:

A = 2πr(r+h)

A = 2πr² + 2πrh

2πrh = A - 2πr²

     h = (A-2πr²)/2πr

         =A/2πr - 2πr²/2πr

         =A/2πr - r

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
