You're correct DS......7*pi*y^2 would be the answer for the area of 7 circles !!!
good job !!!
Think about this guys.....what's the "formula" for the area of a circle with a radius of "r" ???
What would be the way to find out the area of 7 of these circles???
OK......she needed only 1/2 of a cup......but she used 2/3 of a cup.....is 2/3 larger or smaller than 1/2???
What's the answer??? (rosala....you were close to the answer, but you made a small mistake...)
Wait a sec, guys......
She needed 1/2 of a cup and she used 2/3 of a cup.........ask yourselves the question, first....did she go over??? How would I find out???
(We don't need any pics !!!)
I don't think we need any pics, rosala !!!!
Read it again, and see if you know how to find the answer......
DS and rosala.......I think rhat both of you might be able to do this one........give it a try!!!!
Thanks, DS !!!
Nice answer, rosala !!!
I like to think of the Associative Property this way:
Sometimes, the first two "friends" associate together, so we have
(a + b) + c
And other times, the last two "friends" associate together, so we have
a + ( b + c) !!!!
OK....
1 cup has 128 grams
So......1/2 of a cup must have half of that = 64 grams
If she used 2/3 of a cup and only need 1/2 of a cup, what would be the correct answer???
Can you do this one??? (You won't learn anything if I just give you the answers.....)
mari379, I'm going to tell you how to find the answer:
Mutiply the base times the height and divide that answer by 2.
Remember that your answer will be _________ cm2
