Given the figure of a square pyramid
The area pf the base =area of the square of side 14 in =
the area of the sides = 4 times the area of a triangle of a base of 14 in and a height of 12 in
so, the area of the sides =
So, the surface area of the pyramid =
So, the answer will be A = 532 in^2
Answer: 13 whole pieces of wire can be cut from that spool and of wire is left over.
Step-by-step explanation:
Convert from mixed number to improper fraction. To do it you must multiply the whole numbe part by the denominator of the fraction and then add the product to the numerator. The denominator does not change. Then:
Since the spool contains 100 inches of wire, you must divide this lenght by :
Convert from improper fraction to mixed number:
- When you divide the numerator 800 by the denominator 59, the quotient is 13 (this is the whole number part)
- The remainder is 33 (This is the numerator of the fraction).
- The denominator does not change.
Then:
Therefore 13 whole pieces can be cut from that spool.
The amount of wire left over is:
