Step-by-step explanation:

A circle is 360 degrees. Comedy is 15%. We are asked in words, "How many degrees is 15% of 360?"

Let "how many degree" be x; the word "is" means =; 15% as a decimal is .15; the word "of" in this context means to multiply; and 360 is just 360. Putting all that together into an equation that we can solve for x:

x = .15(360). Multiply to get

x = 54 degrees

The Miguel traces a circle with the radius of 25 cm like the one shown. He will color the shade section what is the area of the

Scilla [17]

Answer: The area of shaded section is 491.07 cm²

Step-by-step explanation:

Given: Radius of the circle = 25 cm

Now as shown in figure the shaded region is a quadrant.

Therefore the central angle is 90°

Now as we know

Area of sector is given by

$Area= \pi r^2 \dfrac{\theta}{360^\circ}$ where r is radius and $\theta$ is central angle

So we have

$Area = \dfrac{22}{7} \times (25)^2\times \dfrac{90^\circ}{360^\circ} \\\\\Rightarrow Area= \dfrac{22}{7} \times 625 \times \dfrac{1}{4} \\\\\Rightarrow Area= \dfrac{11}{7} \times 625 \times \dfrac{1}{2} = 491.07cm^2$
