Suppose a metal ring could be placed around earth at the equator.

the metal ring is 12,756.2 km

b) suppose the length of the metal ring is increased by 1 km. would i be able to crawl under the ring, walk under the ring, or drive in a school bus under the ring?

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
