Paige has a garden in the shape of a circle. the radius of the garden is 4 feet. in the center, you place a birdbath with a radius of 1 foot. what is the area left for planting around the bath? use 3.14 to approximate pi.

Ara=pir^2
plantingarea=gardenarea-birdbath
leave in terms of pi first

gardenradius=4
gardenarea=pi4^2=pi16=16pi

plantingarea=garden-birdbath=16pi-pi=15pi

aproxpi=3.14
3.14*15=47.2 ft^2 for planting
