Answer:
123m squared
Step-by-step explanation:
First let's get the area of the square by doing 10*10 to get 100, now let's find the area of the semicircle. We can pretend it is a full circle and then cut it in half. We do the radius which is 5 times, pi which is 3.14 to get 15.7. We then square that to get 246.49. Since we want a semicircle we cut that in half to get 123.245. We add this to 100 to get 123.245. Since we have to round, the answer is: The area of the figure is about 123 m2.
Step-by-step explanation:
Average = 30 mil/h
Period = 10s
Av = 30 ÷ 360 / 3600 ÷ 360
Av = 1/12 mil / 10 sec
<h2>
19 X 33 = 627, justified.</h2>
Step-by-step explanation:
We have,
19 × 33 = 627
Use the fact and justify.
L.H.S. = 19 × 33
= (20 - 1) (20 + 13)
Using the identity,
(x - a)(x + b) = - (a - b)x - ab
Here, x = 20, a = 1 and b = 13
= - (1 - 13)20 - 1(13)
= 400 - (- 12)20 - 13
= 400 + 240 - 13
= 640 - 13
= 627
= R.H.S., justified.
Thus, 19 X 33 = 627, justified.
