Question

Determine a área e volume de um cilindro circular reto que possui altura igual a 10 cm e raio da base 2 cm.

Answer 1

$\large\boxed{\begin{array}{l}\rm A_T=2\pi r(r+h)\\\rm A_T=2\pi \cdot2(2+10)\\\rm A_t=4\pi\cdot12\\\rm A_T=48\pi~cm^2\\\rm V=\pi r^2\cdot h\\\rm V=\pi\cdot2^2\cdot10\\\rm V=40\pi\,cm^3\end{array}}$
