The working out would be-
Pi x radiussquared
Pi x 64 = 201.0619298297468
Rounded to 2 decimal places =
201.06 feet2
N= (3/2) / (1/4) = (3/2) x (4/1) = 6
'divided by a' is 'multiplied by 1/a' when a is not zero.
5 9/16 - 4 1/2= 1 1/16
I got this because you have make the fractions denomenators equal to subtract them. Once you find how to make them equal you need to mutiply the top numbers the same as the bottom so you can make the new fractions that are equal to the ones before. Then you subtract them and the wholes as well. LOOK BELOW.....
9 x1 9
_ = _
16 x1 16
1 x8 8
_ = _
2 x8 16
9/16-8/16= 1/16 of extra miles
5-4=1 of extra miles
1 and 1/16 of extra miles on monday
391/5
(390+1)/5
(5*78 + 1)/5
78 + 1/5
78.2
