What is the surface area of a cone with diameter 28 cm and height 22 cm in terms of pi?a. 196 pi cm^2b.365 pi cm^2c.561.1 pi cm^2d.2202.8 pi cm^2

The surface area of a cone equation is something really annoying to type out so look at the picture. radius=1/2diameter so r=14. h=22 Plug in the equation to get 561pi.
Just use ur calculator.
