Find the circumference of a circle whose area is 24pi ft^2

Mathematics
2 answers:
Vsevolod [243]3 years ago

Area = 24pi ft^2 = pi * r^2
This gives r = root24


Circumference = 2pi * r
= 2pi * root24
= 4pi * root6


Hope I'm able to help you.

Answer:

30.76 ft^{2}

Step-by-step explanation:

To calculate the circumference of a circle you just have to multiply the diameter by pi.

C= D*\pi

And in order to calculate the value of the diameter you have to clear the formula for the area.

A= r^{2} *\pi

r=\sqrt{\frac{24 \pi }{\pi } }

r=\sqrt{24}

r=4,89

Once we get the radius, we only have to calculate the diameter:

D=2r=9,79

now we just calculate the circumference:

C=D*\pi= (9.79)(3.14)= 30.76

Write an expression for the cost of 1 uniform, add $13, $11 and $8 .
Liula [17]

Answer:

Hey there!

Let the cost of one uniform be c, so the expression becomes

c+13+11+18

Thus, we have c+42

Determine the truth value of the statement if the domain for all variables is the set of nonnegative integers.
Nadya [2.5K]

The domain for all variables of the set of nonnegative integers given is true.

<h3>How to explain the truth value?</h3>

From the information given, we are given ∃n∀m(m< n). This implies that for all m, there exists n such that m × n where m and n are non negative integers.

This statement is true because for any non negative integer, the least value is zero and the set is unbounded.
