Answer: 336.14 cm²
Step-by-step explanation:
To find the area of the rectangle after being cut, we want to find the area of the two semicircles and subtract it from the area of the rectangle. The area of the rectangle is just base times height, or 35cm times 14cm = 490cm² . Since there are two semicircles with the same diameter, we can just solve for the area of a circle and subtract it. To find the area of the circle, we need the radius, which we get by dividing the diameter by 2. After that, we calculate the radius to be 7cm, squared and multiplied by 3.14 (area of a circle) to get 153.86 cm². Subtract the areas, and we get 490 - 153.86 = 336.14 cm²
Answer:
C. AB/XY = AC/XZ
Step-by-step explanation:
Dilation:
A dilation is a transformation that produces an image that is the same shape as the original, but is a different size. The original figure either stretches or shrinks by a certain factor.
In the problem, the dilation is by a factor of 5 and we can see that ABC shrinks to form XYZ.
So, ABC and XYZ are similar triangles which means that the ratio of their corresponding sides will be equal:
AB/XY = AC/XZ = BC/YZ = 5
The answer is 4.
36/63 = 0.57
4/7 = 0.57
Answer:
Option A
A B C D
Step-by-step explanation:
Line of symmetry means that line which cut anything into two two halves.
It could horizontal, vertical and diagonal.
A - vertical line of symmetry
B - horizontal line of symmetry
C - horizontal line of symmetry
D - horizontal line of symmetry
And it is an example of Spherical symmetry:
If the organism is cut through its centre, the resulting parts look the same.
