Answer:
the answer for this question is 15/14
to find area the formula is area = l×b
here length is 1 1/4 and breadth is 3/4 so l×b = 1 1/4=5/4 so 5/4×3/4=15/14
Answer:
Surface area of cone is ![502.4\ ft^2](https://tex.z-dn.net/?f=502.4%5C%20ft%5E2)
Step-by-step explanation:
Given:
radius of a cone (r) = 8 feet
slant height of cone (l) = 12 feet
We need to find the surface area of cone.
Total surface area of cone = Area of circle
Area of curved surface
Now we know that,
Area of circle = ![\pi r^2](https://tex.z-dn.net/?f=%5Cpi%20r%5E2)
Area of curved surface = ![\pi rl](https://tex.z-dn.net/?f=%5Cpi%20rl)
Hence Total surface area of cone = ![\pi r^2+\pi rl=\pi r(r+l) = 3.14 \times 8 (8+12)=3.14\times8\times20= 502.4 \ ft^2](https://tex.z-dn.net/?f=%5Cpi%20r%5E2%2B%5Cpi%20rl%3D%5Cpi%20r%28r%2Bl%29%20%3D%203.14%20%5Ctimes%208%20%288%2B12%29%3D3.14%5Ctimes8%5Ctimes20%3D%20502.4%20%5C%20ft%5E2)
Surface area of cone is
.
The answer would be c.127
