Can anyone solve this math question

12.6 units²

Step-by-step explanation:

Since PX is a tangent to the circle then OP  and PX are at right angles.

A ΔOPX = 12, thus

OP × PX = 12, that is

6OP = 12 ( divide both sides by 6)

OP = 2 ← radius of circle

Area of circle = πr² = π × 2² = 4π ≈ 12.6 units²

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%
