What is the surface area of a cone that has a radius of 5 units and a height of 10 units? Use 3.14 for π and round your answer to the nearest whole number. 254 units2 300 units2 314 units2 384 units2

Surface area of a cone = 254 unit² (Approx)

Step-by-step explanation:

Given:

Radius(r)=  5 unit

Height(h) = 10 unit

Find:

Surface area of a cone

Computation:

Surface area of a cone = πr(r + √h²+r²)

Surface area of a cone = (3.14)(5)(5 + √10²+5²)

Surface area of a cone = 15.7(5 + √100+25)

Surface area of a cone = 15.7(5 + √125)

Surface area of a cone = 15.7(5 + 11.18)

Surface area of a cone = 15.7(16.18)

Surface area of a cone = 254.026

Surface area of a cone = 254 unit² (Approx)

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
