radius of the cylinder​

Answer 1

$\huge{\mathcal {\purple {A}\green {n}\pink {s}\blue {w}\purple{e}\green {r}}}$

As we know the formula see below how i solve:-

$\frac{1}{2} = 2\pi \times r \times h \div 2\pi \times r + 2\pi \times r \\ \frac{h}{h + r} = \frac{1}{2} \\ h = r$

1:1

Answer 2

Answer:

As we know the formula see below how i solve:-

$\begin{gathered} \frac{1}{2} = 2\pi \times r \times h \div 2\pi \times r + 2\pi \times r \\ \frac{h}{h + r} = \frac{1}{2} \\ h = r\end{gathered}$
