Answer:
1055.04 cm³
Step-by-step explanation:
Given that,
Height of a cylinder, h = 16 cm
Radius of the cylinder, r = 5 cm
The height of a cone, h' = 12 cm
The radius of a cone, r' = 4 cm
The volume of the cylinder will be :

The volume of a cone is given by :

Volume of the air surrounding the cone Inside the cylinder = 1256 - 200.96 = 1055.04 cm³
Hence, the required answer is equal to 1055.04 cm³.
Answer:
Model 1 represents 85% shaded area.
Step-by-step explanation:
Here, each model consists of equal sized rectangles.
Please refer to attached figure to know the model number.
Model 2 (on top right of question figure) contains a total of 20 such rectangles out of which 13 are shaded. As per formula of percentage:

Model 3 (on bottom left of question figure) contains a total of 16 such rectangles out of which 10 are shaded. As per formula of percentage:

Model 4 (on bottom right of question figure) contains a total of 16 such rectangles out of which 13 are shaded. As per formula of percentage:

Model 1 (on top left of question figure) contains a total of 20 such rectangles out of which 17 are shaded. As per formula of percentage:

Hence, model 1 is the correct answer.
Answer:
87 cm²
Step-by-step explanation:
there is 1 triangle and 1 rectangle in the diagram. so you have to find the area of the both polygons and sum up to find the total area of polygon
area of triangle formula:

1) area of triangle AED
base = 12 cm
height = 4.5 cm
area:

area of rectangle formula:

2) area of rectangle ABCD
length = 12cm
height = 5 cm
area:

3) area of whole polygon
= area of triangle AED + area of rectangle ABCD
= 27 cm² + 60 cm²
= 87 cm²
