Since it's a wall, I'm guessing it will only have access to half the circle? Therefore:
<em>Circle area formula: </em>πr²
<em>Radius:</em> 12/2 = 6ft
<em>Our case:</em>
(π * 6²)/2 =
36π/2 =
18π = 56.55ft²
Answer:
Step-by-step explanation:
The student hasn't finished the factoring yet.
<u>He still needs the step:</u>
<u>The next step:</u>
- 0 = 2x + 5, 0 = x + 1
- x = - 2.5, x = - 1
Answer:
Volume=1232cm Surface area=660cm
Step-by-step explanation:
Volume=π x r² x t
=22/7 x 7 x 7 x 8
=1232cm
Surface area=2 x π x r x (r+t)
=2 x 22/7 x 7 x (7+8)
=44 x 15
=660cm
