Question

Suppose that r = 11 cm and h = 14 cm in the right circular cylinder. Find the exact and approximate measures (rounded to two decimal places, using your calculator value of ) for each of the following.A right circular cylinder has a radius of the top circular base labeled r and an altitude labeled h.(a)lateral area (in square centimeters)exact cm2approximate cm2(b)total area (in square centimeters)exact cm2approximate cm2(c)volume (in cubic centimeters)exact cm3approximate cm3

Answer 1

Given the following question:

Radius = 4

Height = 14

Formula for volume of a cylinder:

$V=pir^2h$$\begin{gathered} V=pi(4)^2(14) \\ 4^2=4\times4=16 \\ V=pi(16)(14) \\ 16\times14=224 \\ V=pi(224) \\ pi\times224=703.716754 \\ V=703.716754 \\ 703.716754=exact \\ 703.716754 \\ 6>5 \\ 703.72=aprox \end{gathered}$
