C is the answer................
Answer:
2π m.
Step-by-step explanation:
Arc XY is 1/4 of the circumference of the circle
= 1/4 * 2π * r
= 1/2 π * 4
= 2π m.
Answer:
48, 54 and 60
Step-by-step explanation:
Let the three multiples be 6x, 6(x+1) and 6(x+2) respectively.
6x+6(x+1)+6(x+2)=162
6x+6x+6+6x+12=162
18x=144
x=8
Therefore, the three multiples are 6(8), 6(8+1) and 6(8+2)
i.e. 48, 54 and 60
Y=4 because y is 4 all the time
