Question

Find the surface area of the figure shown,
correct to 2 decimal places.

Answer 1

Answer:

$230.73m^2$

Step-by-step explanation:

$A=2a^2+4ah=2*4^2+4*4*4=96m^2$ (square prism)

$A=2\pi rh+2\pi r^2=2*\pi *4*9+2*\pi *4^2 = 326.73m^$(cylinder)

$326.73-96=230.73m^2$ ($\frac{3}{4}$ cylinder)
