Answer:

Area of figure = 122 ft²

Step-by-step explanation:

I have divided the shape into rectangles and triangles. Then I will find the area of each shape. Lastly, I will sum up all the areas to find the area of the shape. The first picture shows the sides of the shape. The second picture shows the area of the divided shapes. Please look at the pictures to understand better. We now know the area of the figure, which is 5 + 75 + 42.

Area of figure = 5 + 75 + 42
=> Area of figure = 122 ft²

Hence, the area of the figure is 122 ft².

The volume of a cylinder is 156 x cm3. What is the volume of a cone with the same base and height as the cylinder?

Flura [38]

Answer: SECOND OPTION (52 cm³)

Step-by-step explanation:

The formula for calculate the volume of a cone is:

$V{co}=\frac{1}{3}r^{2}h\pi$

Where r is the radius and h is the height.

The formula for calculate the volume of a cylinder is:

$V{cy}=r^{2}h\pi$

Where r is the radius and h is the height.

As you can see, the difference between the the formulas is that r²hπ of the cone is divided by 3. Therefore, if you know the volume of the cylinder and you know that the cone has the same base and height as the cylinder, you have to divide the volume of the cylinder by 3 to obtain the volume of the cone.

Therefore, the result is:

$V{co}=\frac{156cm^3}{3}=52cm^3$
