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:
5√3 is the simplified radical expression.
Answer:
3(3x^2 + 5)
Step-by-step explanation:
step 1: find out the greatest common factor (GCF) of the number 9 and 15
ex: 9x^2 + 15x (3 * 3x^2 + 3 * 5)
step 2: factor out the common term 3
ex: 3 * 3x^2 + 3 * 5 (3 * 3x^2 + 5)
step 3: simplify the equation
3 * 3x^2 + 5 [3(3x^2 + 5)]
A = (pi * r^2)/2
A = (3.1416 * (14.3/2)^2)/2
A = 80.3 ft^2
