Answer:
B, C and D
Step-by-step explanation:
Ema found the surface area of a cone as:
[tex]S.A = \pi(14^2) + \pi(14)(29)[/tex]
Surface Area of a Cone [tex]S.A.=\pi r^2+\pi rl[/tex]
Therefore:
Radius, r =14 units
Slant Height, l = 29 Units
(B)The diameter of the cone is 28 units.
SInce Diameter =Radius X 2
Diameter = 14 X 2= 28 Units
(C)The base area of the cone is [tex]196\pi$ units^2.[/tex]
Base Area of a Cone [tex]=\pi r^2[/tex]
Since r=14 Units
Base Area = [tex]=\pi 14^2=196\pi $ square units[/tex]
(D)The lateral area is the product of pi, the radius(r), and the slant height(l).
[tex]L$ateral Area of a cone =\pi rl[/tex]
Therefore, B, C andDapplies.
