Answer:
it means the number of pens bought equals 2 times the number of erasers?
Step-by-step explanation:
P = Pens bought so
E equals: Number of erasers so
p = 2e
in word form pens bought = 2 x erasers bought
Radius = diameter/2 = 8/2 = 4m
Area of a circle = pi x r^2 = pi x 4^2 = 16pi m^2 ( exact area) or 50.27 m^2
Circumference = pi x diameter = 8pi m ( exact) or 25.12 m
