Question

Please help me thank you!!! omg pls

Answer 1

first, find slant height

`c = \sqrt{a ^(2) } + b^(2)`

`c = \sqrt{ {56}^(2) } + {33}^(2)`

`c = √(4225)`

`c = 65`

then, find surface area of cone

formula = area of circular base + area of curved surface

`(\pi * {r}^(2) ) + (\pi * r * s)`

= (pi × 33²) + (pi × 33 × 65)

= (pi × 1089) + (pi × 2145)

= pi (1089 + 2145)

= 3234 × pi
