Answer:
<h2>30 mm</h2>
Step-by-step explanation:
The formula of an area of a circle:

<em>r</em><em> - radius</em>
<em />
We have

Substitute:
<em>divide both sides by π</em>
<em>use π ≈ 3.14</em>

The diameter <em>d = 2r</em>.
Therefore

The answer is .018 because you move the decimal 3 back because there is 3 zeros
Answer:
Numerical length of TU = 6
Step-by-step explanation:
A/q,
SU = ST+TU
5x = 4x-3 + 2x
5x = 4x+2x-3
5x = 6x -3
5x-6x = -3
-x = -3
x = 3
Verify:- Putting x = 3 in 5x =4x-3+2x
5(3) = 4(3)-3+2(3)
15 = 12-3+6
15= 9+6
15= 15
LHS =RHS Hence correct
20+48+12+16=96
Surface area=96
