Actually Welcome to the Concept of the Surface Areas and Volumes.
Since, Volume of cone = 1/3 π r^2 h,
here, r = 10 Inches and h= 12 inches, also π =3.14
so, VOC = 1/3 π (10)^2 × (20)
VOC = 1/3(3.14)(100)(20)= 2093.33 inch^3
=> so the volume of the cone is 2093.33 cubic inches.
Answer:
X=20
Step-by-step explanation:
Sin(x+20)=cos(2x+10)
Sin(x+20)=sin(90-(2x+10)
X+20=90-2x-10
3x=60
X=20
Hey there!
The answer to your question is a = s - b - C/2
<u>To solve for "a", we must get "a" on it's own side of the equal sign.</u> We can first subtract "s" from both sides:
<em>0 = a + b + C/2 - s</em>
Then, we can subtract a from both sides:
<em>-a = b + C/2 - s</em>
Finally, we divide both sides by -1, so a is by itself.
<em>a = -b - C/2 + s</em>
And we can rearrange it to the standard form:
a = s - b - C/2
Good luck, and hope it helped! Have a great day!
The area of the trapezoid is 57.5 square inches.
If you draw out the description, you will see that your trapezoid can be divided into a rectangle that is 9 x 5 and an isosceles right triangle with a base of 5 and height of 5.
Just find the areas of both and add them together.
Rectangle:
5 x 9 = 45
Triangle:
0.5 x 5 x 5 = 12.5
45 + 12.5 = 57.5
It’s D )I’m pretty sure it’s D if it isn’t sorry(
