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.

Find the measure of angle QPR.<br> Given<br> m m m Find m
Dennis_Churaev [7]

Since Angle QPS is a straight angle, it equals 180 degrees.

Angles QPR and RPS equal QPS.

Angle QPR + Angle RPS = QPS

(7x-4) + (9x-40) = 180

x=14

Complete the frequency table:
Gala2k [10]

The percentage of students age 15 and above travel to school by bus is 47%

<h3>How to complete the table?</h3>

The table of values is given as:

                     Method of Travel to School

                            Walk/Bike    Bus    Car Row totals

Under age 15                            18                 165

Age 15 and above    65                                 195

Column totals          152          110        98      360

Using the column total of column 1, we have:

Under age 15 + 65 = 152

This gives

Under age 15 = 87

Using the column total of column 2, we have:

Age 15 and above + 18 = 110

This gives

Age 15 and above  = 92

Using the row total of row 1, we have:

Car + 87 + 18 = 165

This gives

Car = 60

Using the row total of row 2, we have:

Car + 65 + 92 = 195

This gives

Car = 38

So, the complete frequency table is

                     Method of Travel to School

                            Walk/Bike    Bus    Car Row totals

Under age 15           87              18      60        165

Age 15 and above    65          92        38        195

Column totals          152          110        98      360

The percentage of students age 15 and above travel to school by bus is:

Percentage = 92/195 * 100%

This gives

Percentage = 47%
