Answer:
90π cm²
Step-by-step explanation:
Given: Radius of circular base= 5 cm
height= 12 cm
Now finding the surface of cone.
Formula; Surface area of cone= 
Where; r= radius
l= slant height
B is the area of base, which is circle.
Area of circle (B)= πr²
Area of circle (B)= 
∴ Area of circle (B)= 
Finding slant height (l)
Formula; 
⇒l = 
∴ l= 
Next, using the formula for finding surface area of cone.
Surface area of cone= 
⇒ Surface area of cone= 
∴ Surface area of cone= 90π cm²
Answer:
The area of a square with side length of 2 inches is 4 square inches.
The area of a circle with radius 1.2 inches is:

That is approximately 4.5 square inches.
Hence, the area of the square (4) is less than {<} that of the circle (4.5)!
Total high fives is 72
<u>Explanation:</u>
Given:
Number of players in team 1 = 9
Number of players in team 2 = 8
A high-five occurs between 2 people of each team
1 player will give high five to 8 players
So, 9 players will give high five to 9 X 8 players
Total high fives = 72
Therefore, total high fives is 72
Answer:
2,268.63
Step-by-step explanation: there are two methods.
1st you can multiply 58.17 by 39.
or the 2nd way is the fish method.
fish method: _/39 and 58.17/1
the 39 and 1 are the hours
the blank and 58.17 are the money
you would multiply 58.17 by 39 and divide by 1.
