For each of the following circumferences, find the radius of the circle. a. \( C=22 \pi \mathrm{~cm} \) b. \( C=10 \mathrm{~m} \) a. \( \mathrm{r}=\square \mathrm{T} \) (Simplify your answer. Type an exact answer, using \( \pi \) as needed.)

3. Construye angulos con las siguientes medidas, Luego, clasificalos según sus medidas. \( \begin{array}{lllll}\text { a. } 25^{\circ} & \text { b. } 85^{\circ} & \text { c. } 68^{\circ} & \text { d. } 150^{\circ} & \text { e. } 100^{\circ}\end{array} \)

3.) WHEA OF IS The ARE OF A SECTOR OF A CIRCLE RADIUS \( r=13 \mathrm{cM} \) IF the CORRESPONPING CENTRAL ANGLF IS \( 30^{\circ} \) ? 4.) WHAT IS TLE AREA OF A SEGTOR OF A CIRULE WHT DIAMETER \( D=28 \mathrm{cM} \) If the GENTRAL ANGLE IS \( 320^{\circ} \) ?

If the height of a cylinder is doubled while keeping the radius constant, how does that affect its volume?

9. Each face of a cube is a square with a side length of 8 centimeters. What is the total area of all of the faces of the cube?

Practics Problems Explofation A sugar cube has a volume of about 1 cubic centimeter. Estimate the size of a box you would need to hold \( 1,000,000 \) sugar cubes?
