$\bf \textit{area of a sector of a circle}\\\\
A=\cfrac{\theta\pi r^2}{360}\qquad 
\begin{cases}
r=4\\
\theta=112
\end{cases}\implies A=\cfrac{112\cdot 16\cdot \pi }{360}\implies \boxed{A=\cfrac{224}{45}\pi}
\\\\\\
A\approx 15.64\\\\
-----------------------------\\\\
\textit{area of a circle is }\pi r^2\textit{ so the other side will be}
\\\\\\
\pi r^2-\cfrac{224\pi }{45}\implies 16\pi -\cfrac{224\pi }{45}\implies \boxed{\cfrac{496\pi }{45}}\implies A\approx 34.68$

6m+4=8m then 4 m. What is the answer

tekilochka [14]

6m+4 = 8m

8m-6m = 4

2m = 4

m = 2

if you are asking for 4m, then it would be 4(2) = 8

What is the diameter of 4cm

Harman [31]

Answer: 8cm

Step-by-step explanation:

If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter.
