Answer:

36π cm

Step-by-step explanation:

C = 2πr

12π = 2πr

12π/2π = 2πr/2π

r =6

Area of a circle = πr²

A= π×6×6

A=36π cm²

If $C=2\pi r$ then $r=6$ and $A=\pi r^2=\boxed{36\pi}$ .

Hope this helps.

Let the ceilings be a & b

and the distance from one corner of the ceiling to the opposite be c

then using Pythagoras theorem

$c = \sqrt{a {}^{2} + b {}^{2} } \\ c = \sqrt{16 {}^{2} + 12 {}^{2} } \\ c = \sqrt{256 + 144 } \\ c = \sqrt{400} \\ c = 20$

hence ,c .°. the distance from one corner of the ceiling to the opposite is 20

Answer: 231

Explanation:

Liwen Celina

5x 6x

5x - 21 = $(\frac{2}{3})$ 6x

5x - 21 = 4x

-4x +21 -4x +21

x = 21

Liwen: 5x = 5(21) = 105

Celina: 6x = 6(21) = 126

Total: 231
