Answer 1

The surface area of a cone that has a radius of 5 units and a height of 10 units 215 square units

How to calculate the surface area of cone

The formula to calculate the surface area of cone is expressed as:

S = πr(r + l)

r is the radius = 5 units

l is the slant height - 10 units

h = √10²-5²

h = √75
h=5√3

Calculate the surface area

S = (3.14)(5)(5 +8.6603 )

S = 215 square units

Hence the surface area of a cone that has a radius of 5 units and a height of 10 units 215 square units
