The total surface area of a right circular cone is 256 square feet. if i slant height of the cone is three times the length of a radius of the base, find the length of a radius

we are given

total surface area is 256

we can use formula

l is slant height

r is radius

we are given

l=3r

so, we can plug it

now, we can plug TA=256

now, we can solve for r

we get
