Find the area of a circle with the diameter of 4.1m. leave your answer in terms of pi

To solve this problem, we must plug in our given values into the formula for the area of a circle: A = πr^2. Because we don't have the radius given to us in this problem, we must find it using what we are given, the diameter, using the equation below:

2r = d

If we plug in the diameter given, we get:

2r = 4.1 m

To solve we must divide both sides of the equation by 2, so that we can get the variable r alone on the left side of the equation.

r = 2.05 m

Now, we can plug in this radius value into our original equation for the area of a circle:

Area = πr^2

A = π(2.05 m)^2

To solve this problem, we must square the value inside the parentheses first.

A = 4.2025π m²

Therefore, your answer is 4.2025π m², because the question asks for the answer in terms of pi (no more simplification is necessary).

Hope this helps!

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%
