Answer:
118.558 cm^2
Explanation:
Ok, a rectangular cube and a Cylinder.
Let's start with the rectangular cube.
SA= 2(lw + lh + wh)
total surface area = 94 cm^2
Now the Surface Area of the of the Cone.
A=2πrh+2πr^2
A=2πrh+2πr^2=2·π·1·5+2·π·1^2≈37.69911 cm^2
Since the cone is standing on top of the rectangular cube, we need to deduct just the area of the circle.
A=πr2=π·12≈3.14159 cm^2
So, 84 cm^2 + 37.69911 cm^2 - 3.14159 cm^2
Sum the quantities:
84 cm^2 + 37.6991 cm^2 - 3.14159 cm^2
Sum the numbers 84 + 37.7 - 3.142 = 118.558:
Answer: 118.558 cm^2
