Answer:
$2942.27
Step-by-step explanation:
Given the circumference of a circle, we can get the radius which will then help us get the area and finally estimate the cost of tiling.
C=2πr
Where C is circumference and r is radius
Making r the subject of the formula then
r=C/2π
Substituting 157 ft for C then
r=157/2π=24.9873260654276 ft
Area, A is given by A=πr²
A=π*(24.9873260654276)²=1961.50509613606
Rounded off, the area is 1961.51 ft²
Given the cost per unit square foot as $1.5 then the overall cost will be
$1.5*1961.51=$2,942.265
Rounded off as $2942.27
The cost is $2942.25.
It is a special kind of ellipse whose eccentricity is zero and foci are coincident with each other. It is a locus of a point drawn at an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.
Given
The circumference of about 157 feet.
The cost to cover 1 square foot with mud is $1.50.
Let radius be the r
circumference = 2π×r
157 = 2π×r
r = 24.99 feet
Then the area of the circle will be
Area = π×r²
Area = π×24.99²
Area = 1961.5 feet²
Then the cost will be
Cost = 1.5 x area
Cost = 1.5 ×1961.5
Cost = 2942.25
Thus, the cost is $2942.25.
