Answer:
the answer is B
Step-by-step explanation:
Answer:
The sine = 0.2724 and the cosine = -0.9615 to 4 decimal places.
Step-by-step explanation:
The point (-7,2) is in the second quadrant .
The sine is positive and the cosine is negative,.
The hypotenuse of the triangle in the second quadrant = √((-7)^2 + 2^2)
= √53 ( by Pythagoras), the opposite side = 2 and the adjacent side = -7.
So the sine of the angle is 2 /√53 and the cosine is -7/√53.
or 0.2724 and -0.9615 to 4 decimal places.
19.625cm squared because you have to divide the diameter by 2 to get the radius.
area of circle=pi times radius times radius
=3.14 times 2.5 times 2.5
=19.625cm squared
16 = 48/3
48 divided by 2 = 24
