Answer: 48π ft2
Step-by-step explanation: The formula for area of a circle is A = πr2. The radius of each rug is 4 feet. We substitute 4 into the formula and we get 16π ft2. Multiply by three to find the total area covered is 48π ft2
Answer is D.) 48π ft² Given: 3 circular rugs. radius: 4 ft Area of a circle = π r² A = 3.14 * (4ft)² A = 3.14 * 16ft² A = 50.24 ft² Total area of 3 rugs 50.24 ft² * 3 rugs = 150.72 ft² Equation leaving π. 150.72ft² ÷ 3.14 = 48ft²D.) 48π ft²

Answer:
x=amount invested at 7%
2x=amount invested at 8%
3x=amount invested at 9%
interest=principal*rate*time (time=1 year)
$150=0.07x+0.08*2x+0.09*3x
$150=0.07x+0.16x+0.27x
$150=0.50x
$1500=5x
x=$300 invested at 7%
2x=$600 invested at 8%
3x=$900 invested at 9%
