Can you please help me with this problem

vagabundo [1.1K]

$\bf \begin{cases}
\textit{area of a circle}=\pi r^2
\\ \quad \\
circumference=2\pi r
\end{cases}
\\ \quad \\

12.56=\pi r^2\implies \cfrac{12.56}{\pi }=r^2\implies \sqrt{\cfrac{12.56}{\pi }}=\boxed{r}
\\ \quad \\
thus
\\ \quad \\
circumference=2\pi \boxed{r}\implies 2\pi \boxed{\sqrt{\cfrac{12.56}{\pi }}}$

If sector area of the shaded circle garden is 8π, and radius of the circle garden is 8 inch. Below figure represent the given sc

otez555 [7]

Answer:

The measurement of the central angle AOB is 45 degrees

Step-by-step explanation:

To solve this problem, we will have to work with fractions.

We will get the fraction of area the shaded portion is when compared to the whole garden.

First of all, we will need to calculate the area of the garden which is $\pi r^{2}$

in this case, our radius is 8 inches.

Next, we will compare the area of the sector to the area of the garden. This will be

This will be the shaded area/ area of the whole garden

= $\frac{8\pi}{\pi8^{2}}$

$=\frac{1}{8}$

We will now convert this ratio to an angle by multiplying it by 360 degrees.

This will be:

$\frac{1}{8}\times 360 = 45 degrees$

The measurement of the central angle AOB is 45 degrees

Please answer it in two minutes

Reil [10]

Answer:

61 degrees.

Step-by-step explanation:

As long as the two figures are congruent, angle P corresponds to angle T, angle [cut off but it says 93 degrees] corresponds to angle U, angle N corresponds to angle V, and angle M corresponds to angle S.

Since we already have the value of T, we know the value of P. The measure of angle P is 61 degrees.

Hope this helps!
