Answer:
11:40
Step-by-step explanation:
First, we need to calculate the circumference of both.
The circumference of a circular object can be calculated as 2πr
The circumference of the earth is thus 2 * 3.142 * 6371 = 40,030 = approximately 40,000Km
The circumference of the moon = 2 * 3.142 * 1737 = 10,913 = apprx 11,000
The ratio of the circumference of the moon to that of the earth is 11,000:40,000 = 11:40
Answer:
1.1 : 4.
Step-by-step explanation:
Given:
rmoon = 1737 km
rearth = 6371 km
Circumference of a circle, C = 2pi × r
Cearth = 2pi × 6371
= 4.0 × 10^7 m
Cmoon = 2pi × 1737
= 1.1 × 10^7 m
Ratio of Cmoon to Cearth
= 1.1 × 10^7 : 4.0 × 10^7
= 1.1 : 4.
