1.
The larger gear will have turned through an arc equivalent in length to the smaller circle's circumference. Thus:
2πr(small) = r(large)∅
2π(2) = 8∅
∅ = π/2 = 90°
2.
The distance covered by the larger gear will be:
C = 2πr
C = 2π(8)
C = 16π
Per revolution, the smaller wheel covers:
C = 2πr
C = 2π(2)
C = 4π
Number of revolutions of smaller wheel = 16π / 4π
Number of revolutions = 4
Step-by-step explanation:
The number divisible by 10 need to be even and divisible by 5, because the prime factors of 10 are 5 and 2. So, it means that for the number to be divisible by 10, the last digit needs to be a zero.
Answer:
Step-by-step explanation:
the lat answer for the first picture correct just plug it in the hihger number for x and then try a larger number y decreases. The same answer for the second one 2
Area = 3.14 * radius^2
Here we have area = 3.14 * 105^2 = 34,618.5 yd^2
