If you look at one of the curves, you can see that it is the circumference of one-fourth of a circle. The center of the two circles are points B and D, therefore the radii are both 8 cm.
The perimeter of half the shape is one-fourth of a circle and there are two of the curves, so perimeter is 0.5 * C where C = 2pi*r
Perimeter = 0.5 * 2 * pi * 8 = 8pi
We can find the area of one of the non-shaded corners by taking the area of the square (8*8 = 64) and subtracting one-fourth of the circle.
64 - (0.25 * pi * 8^2) = 64 - 16pi..
There are two of these corners so multiply by 2 = 128 - 32pi
Now 64 - (128 - 32pi) = Area of shaded region.
Answer:
D 5.46 x 10^10
Step-by-step explanation:
Recall that speed is the rate of change of distance with time and may be expressed mathematically as
speed = Distance/time
Distance = speed * time
Hence given that the speed of light
= 3 × 10^8 meters per second
Time taken for light to travel between the given distance
= 1.82 × 10^2 seconds
substituting the given values
Distance = 3 × 10^8 * 1.82 × 10^2
= 5.46 * 10^(8+2)
= 5.46 * 10^10 meters
Answer:
Similar triangles states the length of the corresponding sides are in proportion.
In a given similar triangles:
Labelled the diagram:
Triangle BAC and triangle DAC are similar.
then;
Corresponding sides:
AB = x units , BC = 5 units, AD = 15 units and DC = BD-BC = 8-5 = 3 units
By cross multiply we get;
Simplify:
Divide both sides by 3 we get;
Simplify:
x = 25 units
Therefore, the value of x is 25 units.
