Answer:
Step-by-step explanation:
<u>For old circular garden:</u>
take the radius as r.
then use the formula to find area of circle: πr² ......this is old garden area.
<u>For new enlarged garden:</u>
the radius is twice the old radius so, radius = 2 * r = 2r ......enlarged radius
now find area for this new garden: π(2r)² → 4πr²
In common fractions: (old garden)/(new garden)
: ( πr² ) / ( 4πr² )
: 1/4
Answer:
7/4 + 9/-5 =
Since the denominator of the second fraction is negative the sign will change from negative to positive
We will get
7/4 - 9/5
First find the LCM
LCM of 4 and 5 is 20
7/4 - 9/5 = 5(7) - 4(9)/ 20
Simplify
We get
35 - 36/20
= -1/20
Hope this helps
