Complete the table. Use 3.14 as an approximation for p.
2. A cylinder has radius r cm and height h cm.
Radius (r cm) Height (h cm) Volume of
cylinder (cm3)
a. 6 12
b. 15
c. 251.2
d. 7 3846.5
e. 3 8478
Radius (r cm) Height (h cm) Volume of
cylinder (cm3)
a. 6 12 1357.44
b. 15 - -
c. - 20 25120
d. 7 3846.5 1421.74
e. 3 8478 72222.54
To calculate the volume of a cylinder, you use the formula V = πr^2h.
Using 3.14 as an approximation for π, we can fill in the table as follows:
Radius (r cm) Height (h cm) Volume of
cylinder (cm3)
a. 6 12 V = 3.14 * 6^2 * 12 = 1354.56 cm3
b. 15 V = 3.14 * 15^2 * h (height not given)
c. 251.2 V = 3.14 * 251.2^2 * h (height not given)
d. 7 3846.5 V = 3.14 * 7^2 * 3846.5 = 5923514.54 cm3
e. 3 8478 V = 3.14 * 3^2 * 8478 = 75,960.24 cm3
Note: To complete the table for options (b) and (c), the height (h) of the cylinder needs to be provided. Without the height, we cannot calculate the volume.
