Mathematics: 1. a hotel is in the shape of a cylinder, with a circular foundation. the circumference of the foundation is 2 times the radius, increased by 235.4 ft. find the radius of the circular foundation. use 3.14 as an approximation for π.2. the circumference, c, of a circle is given. 28pi ft. find the values of r (radius), d (diameter), and a (area) for this particular circle. leave pi π in your answers.

It’s either say 6-4 or 6 - (-4)...

2)The circumference or perimeter of a circle with radius is

$P=2\pi r$ . Given $P=28\pi$ . Therefore,

$2\pi r =28\pi \\ r=14\\ d=2r=28\\ A=\pi r^2 \\ A=\pi (14)^2\\ A=[tex] 196\pi$

Thus the radius is $14\;ft$ , diameter $28\;ft$ and area $196\pi \;ft^2$
