Answer:
The circumference of Dan's circle is approximately 50.27 inches.
Step-by-step explanation:
The length of the circumference (
), measured in inches, is determined by the formula:
(1)
Where 
is the radius, measured in inches.
If we know that 
, then the length of the circumference is:
The circumference of Dan's circle is approximately 50.27 inches.
Answer:
square kilometers
Step-by-step explanation:
The surface area of a sphere can be found using the formula 
. Since the diameter is 3500 km then its radius is half of this. 3500 divided in two is 1,750 units. Substitute r=1,750.
The surface area of the moon is about 38,465,000 square kilometers. Write this is scientific notation using base.
#5
57.8 can be rounded to 60 because 57.8 is closer to 60 than 50 and 81 is relatively close to 80. if we had to estimate the quotient, we would have
60 ÷ 80 = 0.75
#8
2.8 can be rounded to 3 because 2.8 is closer to 3 than it is to 2 and 6 can be left alone because it will make our division easier.
3 ÷ 6 = 0.5
#11
737.5 can be rounded to 700 and 9 can be rounded to 10.
700 ÷ 10 = 100
