On a globe of radius 60cm,find the length in cm the parallel of lat 67 degrees N
the radius at latitude θ is rcosθ
In this case, that would be 60 cos67° = 22.44
So, the circumference at latitude 67° = 2π(22.44) = 147.30 cm

On globe of radius 60cm,find the length in cm of the parallel of latitude 67°north
To find the length of the parallel of latitude 67 degrees North on a globe of radius 60 cm, we can use the formula for the circumference of a circle.
The formula for the circumference of a circle can be written as:
C = 2πr,
where C is the circumference and r is the radius of the circle.
In this case, the parallel of latitude forms a circle on the globe. Since the globe has a radius of 60 cm, we can substitute this value into the formula to find the circumference.
C = 2π(60)
Calculating this expression, we get:
C = 120π
The length of the parallel of latitude 67 degrees North is approximately 120π cm.
To get the exact numerical value, you can use the approximation for π, which is 3.14159:
C ≈ 120 * 3.14159
Calculating this expression:
C ≈ 376.9914
So, the length of the parallel of latitude 67 degrees North on a globe with a radius of 60 cm is approximately 376.9914 cm.
