We are tasked to solve for the lateral area of a right circular cone given that the base diameter measurement is 4 meters and the slant height measurement is 15 meters. To solve this problem, we need to use the formula below: Lateral Area = pi*r (√h²+r²) where r is half of the diameter measurement such as: radius = r = diameter / 2 r = 4/2 r = 2 meters Solving for the lateral area, we have it: Lateral Area = 3.14*2 (√15²+2²) Lateral Area = 94 m²
