Answer:
90π cm²
Step-by-step explanation:
Given: Radius of circular base= 5 cm
height= 12 cm
Now finding the surface of cone.
Formula; Surface area of cone=
Where; r= radius
l= slant height
B is the area of base, which is circle.
Area of circle (B)= πr²
Area of circle (B)=
∴ Area of circle (B)=
Finding slant height (l)
Formula;
⇒l =
∴ l=
Next, using the formula for finding surface area of cone.
Surface area of cone=
⇒ Surface area of cone=
∴ Surface area of cone= 90π cm²
