The circumference of the circle is 37.68 ft
Step-by-step explanation:
Given,
The area of the circle is 113.1 sq ft
To find the circumference of the circle we need to find the radius of the circle first
Formula
The area of circle with radius r is = π
sq unit
The circumference of circle with radius r is = 2πr unit
Let us take the radius of the circle is r ft
According to the problem,
π
or, 
or, 
or, r = 
or, r = 6
Now,
The circumference of the circle is 2×3.14×6 ft = 37.68 ft
Answer:
60%
Step-by-step explanation:
40-16=24
24/40=0.6
0.6*100=60
First, work out the difference (decrease) between the two numbers you are comparing.
Decrease = Original Number - New Number
Next, divide the decrease by the original number and multiply the answer by 100.
% Decrease = Decrease ÷ Original Number × 100
Answer:
5 pounds
Step-by-step explanation:
the volume of the container = 2*1.5*3.5= 10.5cubic foot.
Density of the content = 0.49 pound per cubic foot.
As already know,
Density = mass/ volume.
therefore, mass = density * volume.
mass of the content = 0.49 * 10.5 =5 pounds approximately
Answer:
C) x^2 + y^2 = 16
Step-by-step explanation:
<h2><u>Find the equation </u></h2>
since the radius is 4 this means that anywhere from the center of the circle to the edge of the circle is 4. hence :
place the horizontal line of the radius where y = 0 .
this means that if y = 0 , then x = 4
therefore :
x^2 + y^2
4^2 + 0^2
= 16
<h3><u>hence the answer is C ) x^2 + y^2 = 16</u></h3>
Answer:
Step-by-step explanation:
a=2d+3
b=3d-12
c=a+b so
c=2d+3+3d-12
c=5d-9
