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

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.

repeat the question

step-by-step explanation:

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
