Answer 11

we started learning pi in 5th but i never get no help

Answer 12

The formula for circumference of a circle is
\[C=2\pi r=\pi D\]
where C is circumference
r is radius
D is diameter.

so give that circumference is 42.
if you need diameter then you get
\[D=\frac{C}{\pi}=\frac{42}{\pi}=\frac{42}{3.1415}\]
