Answer:
multiple triangles
Step-by-step explanation:
add the numbers up it adds to 180 which is the sum of a triangle and could create other triangles
We can see from the diagram that the length of the rectangle is 2 lots of the radius of one quarter circle. The width is made up of one radius, therefore the width is half of the length.
This means that the width of the rectangle is 9cm, and the radius of each quarter circle is 9cm.
To find the shaded area, we find the area of the rectangle and subtract from the areas of each circle, which are equal:
A = lw - 1/2(pi x r^2)
A = 9 x 18 - 1/2(81pi)
A = 162 - 81/2 pi
A = 34.8cm (3sf)
a)
F = (K - 273.15) + 32
<u>- 32</u> <u> - 32</u>
F - 32 = (K - 273.15)
(F - 32) = [(K - 273.15)]
(F - 32) = K - 273.15
- = K - 273.15
- 57.6 = K - 273.15
<u> + 273.15</u> <u> + 273.15 </u>
- 215.55 = K
b)
- 215.55 = K
324 - 215.55 = K
108.45 = K
The figures are similar.
the side that is 16 on A is similar to the side that measures 4 on figure B
24 is similar to 6
32 is similar to 8
24 is 4 times 6
24 / 6 = 4
32 is 4 times 8
32 / 4 = 4
and 16 is 4 times 4
16 /4 =4
Figure A is 4 times bigger than Figure B. That is your scale factor.
