Answer:
3. w=P/2-L
Step-by-step explanation:
<u>Given formula:</u>
<u>Solving for w:</u>
- P=2(l + w)
- P/2 = 2(l + w)/2
- P/2 = l + w
- P/2 - l = l + w - l
- P/2 - l = w
- w = P/2 - l
<u>Correct answer choice is:</u>
surface are is basically the area of all the shapes in the prism, so :
(2 x area of the triangles on the sides) + area of upper rectangle + area of bottom rectangle + area of side rectangle
(2x((1/2) x 12 x 5)) + (13 x 10) + (12 x 10) + (10 x 5)
The answer is SAS.
The left side is equivalent to the right side because of the indicating dash. They also share the same angles where the curve marks are. And then lastly they share the same line (the diagonal on the inside) in the shape. Thus making it side angle side
Is it 2:1? That's what I think it is
The correct answer is
<span>2) Calculate the area of the circle. Then, determine the central angle of the sector and divide this angle by 360° to get a fraction. Multiply the area of the circle by this fraction.
area of the circle is calculated by;
area = </span>πr² , where r- radius of circle
<span>the central angle of a circle is 360</span>°. Area of the circle is calculated for central angle of 360°.
<span>Sector is when 2 arms/ radii enclose a central angle between them.
area for 360</span>° = πr²
<span>area for 1 </span>° = area/ 360
<span>area for central angle of sector = area * angle/ 360
the angle of sector is divided by 360 and taken as a fraction .this fraction of the total area of the circle is taken as the area of the sector.
