Answer: 6259.9 cu. cm.

For 6)

Volume, V, for a cylinder:

generally V = A * h = πr^2h, therefore,

V1 = πr1^2h for the volume enclosed by C1

V2 = πr2^2h for the volume enclosed by C2

V = V1 - V2 for the volume of the solid, the tube.

V = π(r1^2 - r2^2)h

Answer:

$27\pi \ cm^{2}$

Step-by-step explanation:

we know that

The area of a circle is equal to

$A=\pi r^{2}$

we have

$r=6\ cm$

substitute

$A=\pi (6)^{2}=36 \pi\ cm^{2}$

Remember that a central angle of $360\°$ subtends for the area of a complete circle

by proportion

Find the area of the circle for a central angle of $270\°$

$\frac{36 \pi}{360} \frac{\ cm^{2}}{degrees}=\frac{x}{270} \frac{\ cm^{2}}{degrees} \\ \\ x=270*36\pi /360\\ \\x=27\pi \ cm^{2}$

Point O is the center of the given circle. What is the measure of YZ?

Rina8888 [55]

Let a chord join YZ, then angle XYZ = 90° and angle XZY = 90 - 54 = 36°
angle OYZ = angle XZY = 36°

Therefore, the measure of YZ = 180 - 36 - 36 = 108°

Answer with explanation plz

Nostrana [21]

The answer is 78.5 because the formula to find area is πr2 so the radius is 5ft π is 3.14 so 3.14 times 5 and the 2 on top of r means the u have to do 5 times 5 which is 25 now it's real simple do 3.14 times 25 which is 78.5 I HOPE THIS HELPS=)
