Step-by-step explanation:
Answer: We minutes hand moves for 20minutes ,it makes 120° central angle
Length=x/360×2πr
=120/360×2×22/7×42
On simplyfing
Length=88cm
Step-by-step explanation:
210/360 = 7/12, meaning the shaded area is 7/12 of the entire circle.
The circle has radius 12 in, so its total area is π (12 in)^2 = 144π in^2.
Then the area of the shaded region is 7/12 of this, or
7/12 * (144 π in^2) = 84π in^2 ≈ 263.89 in^2
Answer:
r =.3 is wrong for 2x = -6. you divide -6/2 which = -3 so r = -3
