Question

COMPETENCEY BASED QUESTIONS 46. R K Agrawal is designing a propylene tank in the shape of a cylinder with hemispherical ends. If the length of the cylinder is to be 20 unit larger than its radius and the volume is to be 33217 cubic unit,
​

Answer 1

Step-by-step explanation:

h = r + 20

vol. of cylinder = 3,3217 unit³

Volume of a cylinder = πr² × h = πr² × (r + 20)

πr²(r + 20) = 33217

r²(r + 20) = 33217/π

${r}^{2} = \frac{33217}{\pi(r + 20)} \\ r = \sqrt{ \frac{33217}{\pi(r + 20)} }$

Answer 2

h = r + 20

vol. of cylinder = 3,3217 unit³

Volume of a cylinder = πr² × h = πr² × (r + 20)

πr²(r + 20) = 33217

r²(r + 20) = 33217/π

\begin{gathered} {r}^{2} = \frac{33217}{\pi(r + 20)} \\ r = \sqrt{ \frac{33217}{\pi(r + 20)} } \end{gathered}

r

2

=

π(r+20)

33217

r=

π(r+20)

33217
