Answer:
0.628 m (This is the correct answer but I cant find it in your options)
Step-by-step explanation:
Radius = 10 cm = 0.1 m
<u><em>Now, The circumference:</em></u>
=> Circumference = 
=> C = 2(3.14)(0.1)
=> C = 0.628 m
Answer:
92.5 %
Step-by-step explanation:
....................
81^2 = 18 ^2 + 80^
6561 = 324 + 6400
6561 = 6724
<span>It is not a right angle, since 18^2 + 80^2 does not equal 81^2.
So,
Using </span><span>The law of cosines:
</span>The largest angle C is opposite to the side c.
Therefore,
<span>c^2 = a^2 + b^2 -2ab cosC </span>
<span>Here,
c^2 < (a^2 + b^2)
cosC must be positive which makes C an acute angle.</span>
Answer:
2/5
0.435
4/9
45.2%
Step-by-step explanation:
The easiest way to do this is converting all to a decimal
2/5 = 0.400
45.2%= 0.452
0.435=0.435
4/9=0.444
Answer:
85
Step-by-step explanation:
You add 17 and 23 and you get 40 so 40=200 and divide 40 and 200 by 5 and so 1/40 =5 so 5x17=85.
sorry if I got it wrong I'm trying.
