A≈21.46
First you find the area of the square
A=a^2 which is
=10^2
A=100
Then you find the area of the circle
A=πr^2
= π(5)^2
A≈78.54
Now you subtract the 78.54 from 100 to get 21.46
You can solve this using proportion.
5 = 4
7 = ?
7(4)/5= 5.6

Answer:
37.5% decrease
Step-by-step explanation:
To find a relative percentage you generally follow the rule of part divided by whole.
$100 / $160 = .625 (62.5%)
So $100 is 62.5% of $160
To find the decrease we need to subtract 62.5% from 100%
100 - 62.5 = 37.5
Answer:
acute angle
Step-by-step explanation:
<h2><em><u>Finding the angle </u></em></h2>
an obtuse angle is an angle which is more than 90° but less than 180°
a right angle is 90°
a straight angle is 180°
an acute angle is less than 90°
is you look at the picture and the definitions you can notice that the angle is less than 90 ° hence its an <u>acute angle </u>
