Answer:

2. one angle is 108, and other is 72

3. x is 12

Step-by-step explanation:

the ratio is 3:2.

3x + 2x = 180

5x = 180

x = 36

36 x 3 = 108

36x 2 = 72

so that is why the two angles re 108and 72.

for the last question, 37 plus 41 plus x = 90

37 plus 41 is 78

90 - 78 = 12

so that is why x is 12.

the volume of a sphere whose diameter is 18 centimeters is ? cubic centimeters. If its diameter were reduced by half its volume

Ghella [55]

A) The formula for the volume of a sphere in terms of its radius (half the diameter) is
$V= \frac{4}{3}\pi r^{3}$
For your 18 cm sphere, the volume is
$V= \frac{4}{3}\pi(9 cm)^{3} = 972\pi \cdot cm^{3} \approx 3054 cm^{3}$

B) If the diameter were reduced by half, the volume would be $(\frac{1}{2})^{3}=\frac{1}{8}$ of the original volume.
