A conical tent made of canvas has a base that is 20 feet across and a slant height of 14 feet.
To the nearest whole unit, what is the area of the canvas, including the floor? Use 3.14 for pi.
:
The radius of the cone: 20/2 = 10 ft
Use the equation
A = pi%2Ar%2As; where s = slant height
A = 3.14%2A10%2A14
A = 439.6 sq/ft
find the area of the floor
A = 3.14*10^2
A = 314 sq/ft
Find the total area of the canvas:
439.6 + 314 = 753.6 sq/ft
