Step-by-step explanation:
Don't you need a key for what K equals to solve this?
Circumference= 2×pi×R
Area= pi× R^2
Since Diameter=2 cm ---> Radius is 2× diameter , so R=4 cm
Circumference=2×3.14×4= 25.12 cm
area=3.14× (4)^2= 50.24 cm^2
Answer:
100
Step-by-step explanation:
The given equation is;
–m + 0.02 + 2.1m = –1.45 – 4.81m
The highest decimal places is 2.
This implies that, we must multiply each term of the equation by
before solving in order to eliminate the decimal.
In that case the equation becomes;
–100m + 2 + 210m = –145 – 481m
Hence the number is 100
