Hey, I'm not sure if I'm wrong or not but wouldn't the answer be c divided by pi? or c/pi

You are correct

It is C divided by PI

Step-by-step explanation:

c=pi x D

Using substitution method replace letters with numbers

12(c)=3(pi) x 4(d)

we want 4(d) the subject of the formula

4(d)=

12/3 =4

so it is 4(d)=12(c)/3(pi)

so D=C/PI

i think the answer is b.

step-by-step explanation:

not 100% sure though.

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%
