Find the circumference and area r = 5 m

stira [4]

Step-by-step explanation:

Let's get our relevant base equations listed out:

d = 2r

area = pi*r²

c = πd

Thus, d=2*5m = 10m, c=π*10m=10π m, and area = 25m²*π

Find the perimeter of the window to the nearest hundredth. also how do you do it?

k0ka [10]

I am assuming the picture is of a stained glass window in the shape of a semicircle.

Answer: 7.71 feet.

Step-by-step explanation: The formula for finding the circumference of a circle is $\frac{1}{2}$ π × d + d.

The diameter is 3 feet. Substitute this into the equation:

$\frac{1}{2}$ π × 3 + 3.

Solve -

3.14 × 3 = 9.42

$\frac{1}{2}$ of 9.42 = 4.71

4.71+3 = 7.71

Round -

The answer is already rounded.

Hope this helped!~
