Question

Plllllllllllease heeeeelp

Answer 1

967.12 cm^2

Explanation:

To find surface area of cylinder:

Find area of cross section x 2 = pi x r ^2 = 153.86 x 2 = 307.72cm^2

Area of curved surface = 3.14 x 14 x 15 = 659.4 cm^2

Total Surface Area = 659.4 + 307.72 = 967.12cm^2

Hope this helps

Answer 2

SA = 967.6 cm²

Explanation:

Surface Area of cylinder =
`2\pi r h + 2\pi r^2`

Where r = 7 cm, h = 15 cm

=> SA = 2(3.14)(7)(15)+2(3.14)(7)²

=> SA = 659.7 + 2(3.14)(49)

=> SA = 659.7 + 307.9

=> SA = 967.6 cm²
