Solve for v 2v+18=16-4(v+7)
Rina8888 [55]
2v+18=16-4(v+7). Take away the parenthesis.
2v+18=16-4v-28. Combine your like terms.
2v+18=-12-4v. Add 12
2v+30=-4v. Subtract 2v
30=-6v. Divide by -6
v=-5. This is your final answer.

A sector of circle C shown below has a radius of 6 centimeters and a central angle that measures 80 degrees. Which expression be
777dan777 [17]

Answer:

The area of the sector is 8*pi cm² or 25.13272 cm².

Step-by-step explanation:

In order to calculate the area of a circular sector we can apply a rule of three in such a way that the circle's area, pi*r²  cm², is related to 360º in such a way that "x" cm² is related to the angle of the sector. We have:

pi*r² cm² ---------> 360º

x cm² ------------> 80º

pi*r²/x = 360/80

360*x = 80*pi*r²

x = 80*pi*r²/360

x = 80*pi*(6)²/360

x = 80*pi*36/360

x = 8*pi cm²

The area of the sector is 8*pi cm² or 25.13272 cm².
