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!

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
