please helpJen slices a cone with a height of 10 centimeters and a radius of 4 centimeters using a plane that is perpendicular to the base and that passes through the vertex of the cone. What is the area of the cross-section in square centimeters?

Accepted Solution

A cone that is sliced through the vertex would make the shape of a triangle.You are told the h eight is 10 cm and the radius is 4 cm. The radius would be half the base, so the base would be 4 * 2 =8 cm. The area of the triangle is found by multiplying the base by the height, then dividing by two.Area = 8 x 10 = 8080 / 2 = 40 square centimeters.
