1.	Find the diameter of a circle whose circumference is 22cm
Answer» $circumference = 2\pi \: r$ $22 = 2 \times \frac{22}{7} \times r$ $\frac{22}{2} \times \frac{7}{22} = r$ $r = \frac{7}{2}$ $r = 3.5 \: cm$ ${\mathbf{\red { \| } {\red {\overline {\underline {\gray { \:brainliest\:if\: it \:helps \:you\: }}}}}}}{\red{ \| }}$ ${\purple{\underline{\overline{\blue{\tt{hope\:it\:will\:help\:you}}}}}}$ ${\orange{\fbox{\underline{\gray{\mathfrak{stay \:blessed}}}}}}$ ${\red{\fbox{\underline{\green{\tt{be \:happy}}}}}}$ ${\red{\fbox{\gray{\fbox{\orange{\ddot{\smile}}}}}}}$
