The surface area of a cone that has a radius of 5 units and a height of 10 units is 254 units.
Surface area of a cone
Using this formula
A=πrl+πr²
Where:
r=radius=5
h=height=10
L=length
l=r²+h²
Let solve Area (A)
A=πr(r+√h²+r²)
A=3.14×5×(5+√10²+5²)
A=3.14×5×(5+√100+25)
A=3.14×5×(5+√125)
A=3.14×5×(5+11.18)
A=15.75×16.18
A=254 units
Therefore the surface area of a cone that has a radius of 5 units and a height of 10 units is 254 units.
