Answer:
No because when you set it up it would be 11/9.4 which equals 1.17
Then you do the other side, 10/8.4 which equals 1.19
And 1.17 doesn't equal 1.19 so they are not similar
Hello from MrBillDoesMath
Answer:
[email protected] = - sqrt(7)/ 4
which is choice B
Discussion:
This problem can be solved by drawing triangles and looking at ratios of sides or by using the trig identity:
([email protected])^2 + (sin2)^2 = 1
If [email protected] = 3/4
, the
([email protected])^2 + (3/4)^2 = 1 => (subtract (3/4)^2 from both sides)
([email protected])^2 = 1 - (3/4)^2 = 1 - 9/16 = 7/16
So...... taking the square root of both sides gives
[email protected] = +\- sqrt(7)/ sqrt(16) = +\- sqrt(7)/4
But is [email protected] positive or negative? We are told that @ is in the second quadrant and cos(@) is negative in this quadrant, so our answer must be negative
[email protected] = - sqrt(7)/ 4
which is choice B
Thank you,
Mr. B

Answer:
5^9
Step-by-step explanation:
Area of Base x Height
Area of a circle is PI x R squared
Radius is 3
Area of Base is 9Pi
9Pi x Height
Height is 6
9pi x 6 =
54 pi.
