The lateral area of a cone is given by L = πrℓ, where r is the radius of the base and ℓ is the slant height. Here, we know L = 555 cm^2 and r = 15.1 cm. Plugging in these values, we get:
555 = π(15.1)ℓ
Solving for â„“, we have:
â„“ = 555/(Ï€(15.1))
ℓ ≈ 11.7 cm
Therefore, the slant height to the nearest tenth of a centimeter is 11.7 cm, which is option B.
The lateral area of a cone is 555 cm^2 the radius is 15.1 cm what is the slant height to the nearest tenth of a centimeter
A. 36.8cm
B. 11.7cm
