Answer:
There are infinity answers to this
Step-by-step explanation:
------------------------------------------------------
Formula
------------------------------------------------------
Area of circle = πr²
------------------------------------------------------
Find Radius
------------------------------------------------------
200.96 = πr²
r² = 200.96 ÷ π
r² = 63.97
r = √63.97
r = 8 km (nearest hundredth)
------------------------------------------------------
Formula
------------------------------------------------------
Circumference = πD
------------------------------------------------------
Find Diameter
------------------------------------------------------
Diameter = Radius x 2
Diameter = 8 x 2
Diameter = 16 km
------------------------------------------------------
Find Circumference
------------------------------------------------------
Circumference = πD
Circumference = π (16)
Circumference = 25.13 km
------------------------------------------------------
Answer: Circumference = 25.13km
------------------------------------------------------
Dear
A distance of one international mile or 1 760 international yards or exactly 1609.344 meters travelled in one hour or exactly 3 600 seconds. 1 Mile per hour = 1.60934 kilometers per hour = 0.44704 meters per second (SI base unit). 1 mph = 0.447 04 m/s.
Also,
1 Centimeter per second is equal to 0.01 meters per second (SI unit).
So, car travels 2235.2 cm per second.
General rule so exg
round 14 to the nearest 10, the answer is 19 becuase 4>5 so round down
if 15 then round to nearest 10=20 because 5<u>></u>5
so tenth digit is the 6
look at the next digit
7
7>5 so round up
34.7
