Answer:
\(13.23375 feet^2\) is the approximate area of the remaining countertop surface
Step-by-step explanation:
Length of the rectangular counter ,l= 5 feet
Width of the rectangular counter ,w = 3 feet
Area of the rectangular counter = A = l × w
\(A=5 feet\times 3 feet =15 feet^2\)
Radius of the circle cut out from the rectangular counter = r
Diameter of the circle = d = 18 inches = 1.5 feet
1 inch =0.0833333 foot
\(r =\frac{d}{2}=\frac{1.5 feet}{2}=0.75 feet\)
Area of the circle :A'
\(A'=\pi r^2=3.14\times (0.75 feet)^2=1.76625 feet^2\)
Area of the remaining counter-top surface: A - A'
\(15 feet^2-1.76625 feet^2=13.23375 feet^2\)
