Answer:
cylinder 1 has a radius of 8 cm
cylinder 2 has a radius of 2.5 cm
Step-by-step explanation:
cylinder 1:
we know... h = 10cm [tex]\pi[/tex] = 3.14 and 2009.6 [tex]cm^{3}[/tex]
plug these values into the volume formula: 2009.6 = (3.14) (r^2) (10)
multiply 10 and 3.14: 2009.6 = (31.4) r^2
divide both sides by 31.4: 64 = r^2
put both sides under a root square: 8 = r
cylinder 2:
we know... h = 10cm [tex]\pi[/tex] = 3.14 and 196.25 [tex]cm^{3}[/tex]
plug these values into the volume formula: 196.25 = (3.14) (r^2) (10)
multiply 10 and 3.14: 196.25 = (31.4) r^2
divide both sides by 31.4: 6.25 = r^2
put both sides under a root square: 2.5 = r
