Answer:
The diameter of the circle is 56 cm.
Step-by-step explanation:
Given : The area of the circle is 2464 cm square.
To find : The diameter of the circle?
Solution :
The area of the circle is defined as
Where, A=2464 cm² is the area,
r is the radius
Substituting the values,
Radius of the circle is 28 cm.
The diameter of the circle is
Therefore, The diameter of the circle is 56 cm.
The answer is G. as per absolute value.
Refrection of point (0, 0) across y = 3 gives point (0, 6)
Refrection of point (0, -6) across the x-axis gives point (0, -6)
Answer:
sin²x = (1 - cos2x)/2 ⇒ proved down
Step-by-step explanation:
∵ sin²x = (sinx)(sinx) ⇒ add and subtract (cosx)(cosx)
(sinx)(sinx) + (cosx)(cosx) - (cosx)(cosx)
∵ (cosx)(cosx) - (sinx)(sinx) = cos(x + x) = cos2x
∴ - cos2x + cos²x = -cos2x + (1 - sin²x)
∴ 1 - cos2x - sin²x = (1 - cos2x)/2 ⇒ equality of the two sides
∴ (1 - cos2x) - 1/2(1 - cos2x) = sin²x
∴ 1/2(1 - cos2x) = sin²x
∴ sin²x = (1 - cos2x)/2
