Answer:
Step-by-step explanation:
area including track=area of 2 semi circles+area of rectangle
=2×1/2×π×46²+86×65
=2116 π+5590
area of grass=2×1/2×π×40²+80×65=1600π+5200
≈10226.55 m²
area of track=2116π+5590-1600π-5200
=516π+390
≈2011.06 m²
To get the answer for how many beads she had before she went to the craft store you do 36 - 19 = 17 and you get 17 beads that she had before she bought the new ones . Your answer is 17. To check ypur answer add 17 + 19 and you get 36
The angle of B is 56.2 degrees
<em><u>Solution:</u></em>
Given is a right angled triangle ABC
From given figure,
AB = 9
CB = 5
We have to find the angle of B
Let the angle of B be 
By definition of cosine,
Here, adjacent = CB and hypotenuse = AB
Therefore,
Taking cos inverse on both sides,
Thus the angle of B is 56.22 degrees
So
Total cost of the workbooks is d
And the number of workbooks is t
Therefore d = 95
95=19t
t=95/19=5
5 workbooks
