<span>A=2πr^2+2πrh
</span>A=π(2r^2+2rh)
π = A / (2r^2+2rh)
32.98 is the answer to that question
1/3m - 1 - 1/2n
= 1/3( 21) - 1 - 1/2 (12)
= 7 - 1 - 6
= 6 - 6
= 0
Answer:
Theresa needs 44 pieces of woods.
Step-by-step explanation:
Given:
Length of wood required to fence = 233 feet
Length of the wood = 11 feet
Number of pieces of wood Samuel needs = 22 pieces.
We need to find number of pieces of wood required by Theresa.
Solution:
Now Given:
Theresa has twice as many feet of wood as Samuel.
So we can say that;
Number of pieces of wood Theresa need is equal to 2 multiplied by Number of pieces of wood Samuel has.
framing in equation form we get;
Number of pieces of wood Theresa need = 
Hence Theresa needs 44 pieces of woods.
