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

The surface area of a cone with diameter 28 cm and height 22 cm in terms of pi is:

        c.     561.1 pi cm²

The diameter of cone= 28 cm

Radius of cone is half the diameter this means that:

Radius(r) of cone= 14 cm

Also, height(h) of cone= 22 cm

We know that the surface area of cone is given by:

Now as we know the value of h and r hence we will substitute these values in the formula to get:

  Hence, the surface area of cone is:  561.1π cm²

22

step-by-step explanation:

it has the same slope and a different y-intercept

hope this : )
