Answer:
The second, third and fifth are true.
Step-by-step explanation:
1) False, the radius is d÷2=8÷2=4 cm
2) True, C = 2×π×r = π×d = 8π
3) True, C = 8π = 8 × 22/7 = 176÷6 ≈ 25,14
4) False, C = 25,14 ≈ 25
5) True, C = 8π = 8×3,14 = 25,12

There is one number greater than 5 on a dice - that is the number 6.
So probability of throwing a six = 1/6.
So it is 42 * 1/6.
pretty sure it's 56 I could be wrong though
Answer: x=4, y=-2
Step-by-step explanation: 4x+y=14, x-2y=8
4x+y-y=14-y
4x/4=14/4-y/4
x=14-y/4-(2y)(4)/4
4(14-9y)/4=(8)(4)
14-9y-14=32-14
-9y/-9=18/-9
y=-2
(14)-(-2)/4
14+2/4
16/4
4
x=4
x=4, y=-2
