The girls in Lana’s troop set a goal to sell 1,000 boxes of cookies this year. There are 13 girls in the troop. At least how many boxes of cookies should each girl sell to reach their goal?

77 boxes

Step-by-step explanation

Hello there! Let's solve this problem together:

First, we will review our numbers.

13 girls have to sell 1,000 boxes.

Now, we will do the math.

We will solve this problem by dividing.

We will keep multiply by one until we reach 1000 or more.

They have to each sell at least 77 boxes.

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)
