Answer:
6.95
Step-by-step explanation:
to find how much stephanie spends for first we will find how much probhjot spends and then subtract 3.45 dollars from that value alvin spends 2.60 dollars
prohbjot spends 4 times as much as alvin or
4× 2.60=10.4
so prohbjot spends 10.4 dollars
stephanie spends3.45 dollars less than prohbjot or
10.4 -3.45 =6.95
so stephanie spends <u>6.95 </u>dollars
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
