157+364= 521 square mm
Step-by-step explanation:
Area of 1/2 circle = 1/2 pi r-squared = 1/2x10x10x3.14 = 157 square mm
Area of trapezoid = (a+b)/2xh = (20+32)/2 x 14 = 364 square mm
157+364= 521 square mm
Answer:
28
Step-by-step explanation:
4.5 pounds
72 ounces
HOW-TO:
1. we know that 1 pound is 16 ounces.
So let's find how many of 16 are needed for 72.
72 ÷ 16 = 4.5
Use that answer and multiply it by the number of pounds per 16 ounces.
You get 4.5 pounds.
One correct answer would be 4 rows of 8 stamps each.
It sounds like you're doing arrays. If you weren't given any options to choose from and you have to create this yourself, then you can use the answer I helped you with.
With arrays there are different examples you can create. The only rule you have to follow is that you have everything shared equally with each row, meaning each row of what you choose can have no more and no less than any other row.
Ex: (given above) 2 rows of 16
4 rows of 8
8 rows of 4
16 rows of 2
