Answer:
The area decreases by 1155.52 square meters
Step-by-step explanation:
a = pi * r ^ 2
d = 2 * r
r = d / 2
r = 96/2
r = 48
a1 = 3.14 * 48 ^ 2
a1 = 7234.56 square meters.
r = 88/2
r = 44
a2 = 3.14 * 44 ^ 2
a2 = 6079.04 square meters.
now we calculate the difference
a1 - a2 = 7234.56 - 6079.04
= 1155.52 square meters
Answer:
P * 196 = 49
Step-by-step explanation:
What percent of 196 is 49
Percent is P
of means multiply is means equals
P * 196 = 49
The answer is D !! 12x !!
To compare fraction sizes, you have to make sure the denominators of the fractions are the same. You must find a number that is a multiple of all the denominators we currently have (15, 3, 12, 9)
The smallest number that fits this is 540
Now you must multiply the numerator and denominator of each fraction by the number that makes the denominator 540
So, for 7/15 , we multiply the top and bottom by 36, since you need to multiply 15 by 36 to get 540. This means the fraction you end up with is 252/540
For 2/3, we multiply the top and bottom by 180, since you need to multiply 3 by 180 to get 540.This means the fraction you end up with is 360/540
For 11/12, we multiply the top and bottom by 45, since you need to multiply 12 by 45 to get 540. This means that the fraction you end up with is 495/540
For 5/9, we must multiply the top and bottom by 60, since you need to multiply 9 by 60 to get 540. This means that the fraction you end up with is 300/540
Now that the hard part is out of the way, you have four fractions: 252/540, 360/540, 495/540 and 300/540. Now, you can arrange the fractions in ascending order just based on their numerator.
So, the order would be: 252/540, 300/540, 360/540, 495/540
Now, for the final step, just convert them back to the original fractions.
So, the final answer is:
7/15, 5/9, 2/3, 11/12

The perimeter of a shape is the distance around it, or all of the lengths of its sides added together. So the perimeter can be represented by s + (s + 4) + 3s.
