Answer: 9.42477796077 square yards
Explanation:
Cone Surface Area Calculation
surface area of cone slant height is 2 radius is 1
To find the surface area of a cone, we need to know the radius and slant height of the cone.
In this case, we are given that the radius (r) is 1, and the slant height (l) is 2. We can use the Pythagorean theorem to find the height (h) of the cone:
l^2 = r^2 + h^2
2^2 = 1^2 + h^2
4 = 1 + h^2
h^2 = 3
h = sqrt(3)
Now we can use the formula for the surface area of a cone:
A = πr^2 + πrl
Substituting the values we know:
A = π(1)^2 + π(1)(2)
A = π + 2π
A = 3π
So the surface area of the cone is 3π
3 times Pi = 9.42477796077
