Daily Check 1.2. 3. 4.

3
Surface Area of a Sphere

4
Volume of a Sphere

5
A sphere is inscribed in a cube of volume 125 cubic meters. What is the surface area and volume of the sphere? Give an exact answer and an answer rounded to the nearest hundredth.

6
Volume = Find the radius. Round to the nearest hundredths.

7
Volume of a Sphere Circumference of Great Circle = 14 cm Find the volume of the sphere. Round to the nearest hundredths.

8
Volume of a Sphere Volume = Find radius. Round to the nearest hundredths.

9
Comparing Ratios

10
Sphere A Sphere B Radius of Sphere ARadius of Sphere B 3 cm6 cm How much bigger? 2 times bigger

11
Sphere A Sphere B SA of Sphere ASA of Sphere B 3 cm6 cm How much bigger? 4 times bigger 36 cm 2 144 cm 2

12
Sphere A Sphere B V of Sphere AV of Sphere B 3 cm6 cm How much bigger? 8 times bigger 36 cm 3 288 cm 3

13
Sphere A Sphere B Radius of Sphere ARadius of Sphere B 3 cm15 cm How much bigger? 5 times bigger

14
Sphere A Sphere B SA of Sphere ASA of Sphere B 3 cm15 cm How much bigger? 25 times bigger 36 cm 2 900 cm 2

15
Sphere A Sphere B V of Sphere AV of Sphere B 3 cm15 cm How much bigger? 125 times bigger 36 cm 3 4500 cm 3

16
There is a pattern that can save you some work!

17
SET UP A TABLE LIKE THIS Times biggerSphere ASphere B RADIUS r SA r2r2 V r3r3

18
If the radius of a sphere is doubled, what happens to its volume? V is 8 times bigger Times biggerSphere BSphere A RADIUS r SA r2r2 V r3r3 r = 2 r 3 = 8

19
If the radius of a sphere is quadrupled, what happens to its surface area? SA is 16 times bigger Times biggerSphere ASphere B RADIUS r SA r2r2 V r3r3 r = 4 r 2 = 16

20
The radius of sphere A is 1 cm and the radius of sphere B is 2 cm. The SA of sphere A is 4 in 2, what is the SA of sphere B? 16 in 2 Times BiggerSphere ASphere B RADIUS r SA r2r2 V r3r3 2 cm r 2 = 4 1 cm 4 r = 2

21
The radius of sphere B is 3 times bigger than the radius of sphere A and the V of sphere A is 10 in 3, what is the V of sphere B? 270 in 3 Times BiggerSphere ASphere B RADIUS r SA r2r2 V r3r3 r 3 = 27 10 r = 3

22
The SA of sphere B is 4 times bigger than the SA of sphere A. If the radius of sphere B is 20 m, what is the radius of sphere A? 10 m Times biggerSphere ASphere B RADIUS r SA r2r2 V r3r3 r 2 = 4 20 r = 2

23
The V of sphere B is 125 times bigger than the V of sphere A. If the radius of sphere B is 45 ft, what is the radius of sphere A? 9 ft Times biggerSphere A Sphere B RADIUS r SA r2r2 V r3r3 r 3 = 125 45 r = 5
