Bismarck and Shannon get into an argument over whose grandma makes the BEST cookies!! They both ask their grandma's to make cookies for their math classes. Shannon's grandma can make 2 batches cookies per hour plus 4 extra batches cookies she made the other day. Bismarck's grandma can make 4 batches cookies per hour. How many hours will it take for their grandma's make the same amount of cookies?

correct answers below:

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.

2y+y=5

add 2y and y
