A circle has its center at the center of a square with 3-inch sides. Find the area of the square not covered by the circle Round
Aleonysh [2.5K]
So in order for us to know the area of the square that is not covered by the circle, we need to find first both the areas of the square and the circle.
So for the area of the square it is A = sxs. And for the circle is A = pi*r^2.
Let us find the area of the square first given that the side is 3 inches.
So A = 3*3
    A = 9 square inches.
Next is the area of the circle. Since the center of the circle is the same with the center of the square, the radius would be 1.5.
SO, A = (3.14)(1.5)^2
       A = 2.25 (3.14)
        A = 7.065 square inches.
Next, we deduct the area of circle from area of square and the result would be 1.935 <span>in². So the answer for this would be option B.
Hope this answer helps.</span>

When Jamie has $200 to purchase skateboard equipment, he will have spent more than 50 percent.

<h3>How to calculate the percentage?</h3>

From the information given, the total amount spent will be:

= $100 + $60 + $30 + $20 + $20 + $50 + $115

= $395

Since Jamie has $200 to purchase skateboard equipment, the percentage will be:

= 200/395

= 0.51

= 51%

100 points if you show how you got the answer!
ludmilkaskok [199]

First, simplify each one.

9.98 x 10^6 = 9980000

7.3 x 10^7 = 73000000

Next, subtract the freight from the aircraft

73000000 - 9980000 = 63020000

Round the decimal point to the first significant digit, and place the amount of place values the decimal point moved to the left as a power sign, over 10.

63020000 = 6.302 x 10^7

6.302 x 10^7 is your answer

hope this helps
