Answer:
To find the circumference of a circle, your equation is 2*pi*radius
C=2*3.14*2 (radius is half of diameter so 4/2=2, 2=radius)
C=12.56 ft
To find the area of a circle, your equation would be pie*r^2
A=3.14*2^2
A=3.14*4
A=12.56 sq. ft
Hope this helps ;)

Answer:
400 pencils
Step-by-step explanation:
So he sold 3/5 of them in the morning and 1/4 of the remainder in the evening
1/4 of 2/5 - (the remainder) is 1/10
3/5 is also equal to 6/10
In the morning he sold 6/10 of the pencils and in the evening he sold 1/10
If he sold 200 more in the morning than we do 6/10 - 1/10
And that is 5/10. So 5/10 is how much more he sold in the morning
5/10 = 200
So 10/10 = 400!
