The radius of the circular surface of a cylinder is 8.4cm and its height is 4.5cm find (×=22/7) About the author Sophia
Answer: solution radius of cylinder=8.4 height =4.5 total surface area of cylinder = [tex]2\pi \: r(r + h) \\ = 2 \times \frac{22}{7} (8.4 + 4.5) \\ = 2 \times \frac{22}{7} \times 12.9 \\ = 81.0857 [/tex] hope it’s helpful Mark me as brainliest and like my answer Reply
Answer:
solution
radius of cylinder=8.4
height =4.5
total surface area of cylinder
=
[tex]2\pi \: r(r + h) \\ = 2 \times \frac{22}{7} (8.4 + 4.5) \\ = 2 \times \frac{22}{7} \times 12.9 \\ = 81.0857 [/tex]
