Question

the height of a solid cylinder 10.5 cm. if the volume is 2112cm3 , then find the radius of calendar
​

Answer 1

Answer:

Right cylinder

Solve for radius

r≈8cm

h Height

10.5

cm

V Volume

2112

cm³

Using the formula

V=πr2h

Solving forr

r=V

πh=2112

π·10.5≈8.00161cm

Answer 2

Answer:

radius = 8 cm

Step-by-step explanation:

volume of cylinder =

$\pi \: r {2} h$

2112cm3 = 22÷7 ×r2 × 10.5 cm

2112 cm3 ×7 ÷22×10.5 cm = r2

14,784 cm3 ÷ 231 cm = r2

64 cm2 = r2

√64 cm2 = r

8 cm = r
