Given:
A diagram of a composite figure.
Radius of cone and hemisphere is 8 cm.
Height of the cone is 15 cm.
To find:
The volume and the surface area of the composite figure.
Solution:
Volume of a cone is:
Where, r is the radius and h is the height of the cone.
Putting in the above formula, we get
Volume of the hemisphere is:
Where, r is the radius.
Putting , we get
Now, the volume of the composite figure is:
The volume of the composite figure is 661.3π cm³.
The curved surface area of a cone is:
Where, r is the radius and h is the height of the cone.
Putting in the above formula, we get
The curved surface area of the hemisphere is:
Where, r is the radius.
Putting , we get
Total surface area of the composite figure is:
The total surface area of the composite figure is 264π cm².
Therefore, the correct option is A.
Answer:
3 1/3 gallons
Step-by-step explanation:
It is more helpful to think of the wall as 5 sections. if two sections used 4/3, by logic one section uses 2/3 (because 4/3 ÷ 2 = 2/3). since there are 5 sections, 2/3 × 5 you get 10/3. turn it into a mixed fraction and you get 3 1/3.
