Radian measure is given by dividing the length of an arc by the radius of a given circle. Such that an arc that subtends an angle of 1 radian to the center of a circle is equivalent to the radius of the circle.
Therefore; θ = s/r where θ is the angle subtended in radians, s is the length of the arc and r is the radius of the circle.
Hence; r = s/θ
= 12π ÷ (4π/7)
= 12 × (7/4)
= 21 inches
5^2=25
25-(2x7^2)
7^2=49
25-(2x49)
49x2=98
25-98=-73
Answer= -73
Answer:
(x, y) = (20, 449)
Step-by-step explanation:
When the equations are in this form, it is easiest to substitute one of the expressions for y into the other equation. That gives ...
21.95x +10 = 22.45x
10 = 0.50x . . . . . subtract 21.95x
20 = x . . . . . . . . .multiply by 2
y = 22.45x = 22.45·20 = 449
Answer:
b
Step-by-step explanation:
Answer:
False
Step-by-step explanation:
The area is found by multiply length with width.
6 & 1 works (interchangeable with either length or width), because:
6 x 1 = 6
Therefore, False is your answer.
