Answer:
The sister is making her wall 3.14 inches longer than Poppy's wall.
Step-by-step explanation:
Poppy and the sister are both making circles basically.
Let the diameter of Poppy's circle be d
Let the diameter of the sister's circle be D
It is given that the diameter of the sister's circle is 1 inches longer than that of Poppy.
D = d + 1
circumference of Poppy's circle = (πd) in.
Circumference of the sister's circle = πD = π(d+1) = (πd + π) in.
So, how much more wire did her sister use than Poppy = (πd + π) - πd = (π) in. = 3.14 in.
Hope this Helps!!!
