Answer:
for second question
first length is 9cm
Area=l*b
= 9cm *9cm
=81<em><u>cm</u></em>
then, For semicircle
radius is 9 cm
area= 1/2*9cm
now , area of two semi circle = 2*1/2*9
= 9 cm
now area of shaded = 81-9
=72
You will need 27 quarters.
1.25*3= 3.75
3.75+3= 6.75
There are 4 quarters in a dollar. 6 dollars = 24 quarters, plus 3 more quarters to equal the .75
5/6 is 1/6 more than 4/6. All you had to do is subtract 4/6 from 5/6 to get <u><em>1/6</em></u>.
6.5 times 4 and 13 times 2
