# What is the surface area of the cone to the nearest whole number? use 3.14 for π. 2,198 m2 3,429 m2 2,813 m2 1,231 m2

The answer to this should be 2888.8

sorry about the quality im not good at writing on computer
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,

Hope this Helps! :)

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

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

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

Hope this helps!
