Answer:
The Volume of large cone is 19.545
greater than the smaller cone
Step-by-step explanation:
Given:
Size of the small cone = 3.5 inches
Diameter of the small cone = 3 inches
Size of the large cone = 3.5 inches
Diameter of the small cone = 3 inches
To Find:
How much greater, to the nearest tenth of a cubic inch, is the volume of the larger cone than the volume of the smaller cone = ?
Solution:
Volume of the small cone :
Radius = 
Radius = 
Radius = 1.5 inches
volume of the cone =
substituting the values,
=>
=>
=> 16.485 
Volume of the large cone :
Volume of the large cone :
Radius = 
Radius = 
Radius = 2.25 inches
volume of the cone =
substituting the values,
=>
=>
=>36.06 
Now ,
volume of small cone - volume of large cone
=>36.06 - 16.485
=>19.545 
Area of ABCE:
12 x 4
= 48cm squared
Area of CDE:
To get the height of the triangle, you subtract 4 from 10.
10 - 4 = 6cm
Base = 12 cm
12 x 6 = 72cm
72 divided by 2
= 36cm squared.
48 + 36 = 84cm squared.
(if it’s asking individual areas, then it’s 48cm and 36cm)
