PLZZ IN NEED HELP!
boyakko [2]

Answer:

18\pi\ cm^2

Step-by-step explanation:

step 1

Find the area of complete circle

The area of the circle is given by the formula

A=\pi r^{2}

we have

r=9\ cm

substitute

A=\pi (9)^{2}

A=81\pi\ cm^2

step 2

Find the area of the shaded region

we know that

The area of complete circle subtends a central angle of 360 degrees

so

using proportion

Find out the area of the shaded region if the central angle is equal to 80 degrees

\frac{81\pi}{360^o}=\frac{x}{80^o}\\\\x=81\pi(80)/360\\\\x= 18\pi\ cm^2

X3+y3+z3=k, what replaces k?
Pachacha [2.7K]

Find x, y, and z such that x³+y³+z³=k, for each k from 1 to 100.

On the surface, it seems easy. Can you think of the integers for x, y, and z so that x³+y³+z³=8? Sure. One answer is x = 1, y = -1, and z = 2. But what about the integers for x, y, and z so that x³+y³+z³=42? … I hope it helps you

How many meatballs are required for a party of 25 adults and 5 children
scoray [572]
Should be 30 meatballs. This is because there are 25 adults and 5 kids. 25+5 = 30. That is the least amount you need. However, most people try to provide at least 2 servings per person. So that would be 60 meatballs. That way each person has two meatballs. Hope this helps, if so please give brainliest:-)
