Step-by-step explanation:

Diameter of circle = 9 ft

Therefore, radius = 9/2 = 4.5 ft

$area \: of \: circle \\ = \pi {r}^{2} \\ = 3.14 \times {4.5}^{2} \\ = 3.14 \times 20.25 \\ = 63.585 \\ = 63.6 {ft}^{2} \\$

please solve the question and show your work find the missing number in 34x =0 show how u got your answer and write full explana

Anastaziya [24]

34x=0
So we need to isolate x. Since 34 is multiplied by x, we need to isolate x by moving 34 over the equal sign. Whenever you move something over the equal sign, the opposite is done. For 34, instead of being multiplied, it will be divided.
34x=0
X=0/34
Then you solve for x
X=0
Hope this helps!
