What would be the circumference of a circle with a radius of 5?

lilavasa [31]

Answer: 10pi

Step-by-step explanation:

C = 2(pi)r

r = 5

2*(pi)*5 = C

10pi = C is the exact answer

If we make 3.14 for the pi substitution, then:

2*3.14*5=C

31.5 = C

I want to know the answer of this question

Molodets [167]

$\bf \textit{circumference of a circle}\\\\
C=2\pi r\qquad 
\begin{cases}
r=radius\\
-----\\
r=5x^2
\end{cases}\implies C=2\pi 5x^2\implies C=10\pi x^2
\\\\\\
\textit{area of a circle}\\\\
A=\pi r^2\qquad 
\begin{cases}
r=radius\\
-----\\
r=5x^2
\end{cases}\implies A=\pi (5x^2)^2\implies A=\pi (5^2x^{2\cdot 2})
\\\\\\
A=\pi (25x^4)\implies A=25\pi x^4$
