Hello!

We know that surface area of a cone = pi(r^2) + pi(rL) where L is the Slant height and R is the Radius and h is Height.
So, 30 is height, and half of 32 is the radius, then we just plug and chug,

An in Short, Your Answer would be 2512, Option "A"

Hope this Helps! :)

The answer is (A) 2,512 m^2

1130.973355 is the answer

Step-by-step explanation:

pi10(10+sqrrt((24^2)+(10^2)))

31.416(10+sqrrt(576+100))

31.416(10+sqrrt(676))

31.416(10+26)

31.416(36)

1130.976

2813 sq.m.

Step-by-step explanation:

Height of cone = 48 m

Diameter of cone = 28 m

Radius of cone =

Slant height l = 50 m

Total Surface area of cone =

=

=

=

Thus the surface area of the cone to the nearest whole number is 2813 sq.m.

Hence Option C is correct.

We know, Surface area of a cone = πr² + πrl
s = 3.14 * (14)² + 3.14 * 14 * 50
s = 615.44 + 2198
s = 2813.44 m²

In short, Your Answer would be Option C

Hope this helps!
