Answer:
133.96 meters squared
Step-by-step explanation:
To calculate the area of a circle, simply multiply the radius squared, by pi.
A = pi x r^2
A = pi x 6.53^2
A = pi x 42.6409
A = 133.9603382
The area of the circle is approximately 133.96 meters squared.
Hope this helps! :)
The first option :
Multiply the first equation by 8 and the second equation by 2
would not result in the elimination of the variables in this system
Number 3 would be y=4x.
Number 5 would be 9 1/24 for the left side and 133/8 for the right side.
First, convert the 65% to a real mathematical number. For percents, this is always done by dividing the 65% by 100%, or 65% / 100% = 0.650.
Second, find out what 65% of $60 is. This is the amount of the sale discount. This is always found by mulitplying 0.650 by the item's cost $60, like this:
0.650 x $60 = $39.00.
So for this sale, you'll save $39.00 on this item.
This means, the cost of the item to you is

18÷19=0.94736....................
