In the figure, the centre C(a, b) of the circle lies on the straight line L1: x+3y-14=0. L2 is another straight line, which is parallel to L1, touching the circle at the point A(4, 10). a) show that 3a-b=2

Show working out thanks

dont trust me im no expert these losers made me fail a test bro this sucks

step-by-step explanation:

22.83 repeating

step-by-step explanation:

137 ÷ 6 is 22.8333333 therefore we understand that 3 is repeating.

happy to

pls mark as brainliest

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
