A roof on a castle tower is shaped like a cone with a diameter of 12 feet and has a slant height of 13 feet one bundle of Shingl
es covers 32 ft.² how many bundles should you buy to cover the roof? What is the surface area of the roof ?
1 answer:
Answer:
Step-by-step explanation:
d = diameter = 12ft
r = d/2 = 12/2 = 6ft
Slant height = 13ft
Surface area of cone = π r 2 + π L r
Where L is the slant height of the cone π = 22/7
SA = 22/7×6×6+22/7×13×6
SA = 113.14+245.142
SA = 358.28ft^2
If one bundle of shingle covers 32 ft.²
Hence,358.28ft^2 = 358.28ft^2/32 ft.²
= 11.196
= 11.2 bundles

Step-by-step explanation:
Answer:
here, Area of s circle is given by;
A=πr²
but, A=1256.00 sq feet and π=22/7
thus, r=√(A/π)
⇒r=√(1256.00/3.142857143)
thus, r=399.64feet
