Question

Find the area of a vertical cross section through the center of the base of the cone Hint use the formula A= 1/2 bh

Answer 1

Given the figure of cone

The vertical cross section will be a triangle

Base of the triangle = b = 12 cm

Height of the triangle = h = 32 cm

Area = A

$A=\frac{1}{2}\cdot b\cdot h=\frac{1}{2}\cdot12\cdot32=192\operatorname{cm}^2$
