B. 65.8
To find the slant height of the cone, we can use the Pythagorean theorem.
The slant height (l) can be found by using the formula l = √(r^2 + h^2), where r is the radius and h is the height of the cone.
Substitute the values given in the formula: l = √(24^2 + 70^2)
l = √(576 + 4900)
l = √5476
l = 65.8
Therefore, the slant height of the cone is 65.8cm. Option B.
