Here’s the answer w explanation :)
1.) D = 2pi * d * A / 360 degrees; Where:
pi = 3.14;
d = distance or 56,000,000 km (5.6x10^7 to standard notation)
A = angular size in degrees or .00688 degrees (.00012 radian to degrees)
D = 2(3.14) * 56,000,000 * .00688 / 360
= 6.28 * 385,280 / 360
= 2,419,558.4 / 360
D = 6,720.996 or 6,721
Therefore, 6,721 km. is the approximate diameter of Mars.
2pie x r= total arc length of a circle
It would be 10.932 years or 10.9 to the tenth
25,000
Step-by-step explanation:
i learned by saying 4 or less let it rest, 5 or more raise the score.After you round everything to the right of the digit you rounded turns to zero or stay the same depending on the number.
