Answer 2

Answer:

here is the ans mark me the branist pls

Step-by-step explanation:

The Formula for Surface Area of a Cone

The circumference of the base of the c o n e = 2 π r cone = 2\pi\; r cone=2πr, where r is the base of the radius of the circular base. The area of the circular base = π × r 2 \pi \times r^2 π×r2.
