Answer:
A. 13 cm
Explanation:
here the total diameter is given 4 cm,
here the radius then will be 2 cm.
use the formula of circumference of circle = 2πr ........where r is the radius
using the formula: 2 * π * 2 = 4π = 12.57 = 13 cm.
The first digit can be any one of the 10 available digits.
. . . For each one . . .
The second digit can be any one of the 9 unused others.
. . . For each one . . .
The third digit can be any one of the 8 unused others.
. . . For each one . . .
The fourth digit can be any one of the 7 unused other.
So the total number of possible choices is
(10 x 9 x 8 x 7) = 5,040 possible PINs
Earth’s diameter is 7,918
Pluto’s diameter is 1,476
7,918 divided by 1,476 is approximately 5.36 which rounds to 5
The answer is Earth is 5 times larger that Pluto
