Correct Answer: A
Solution :
Circumference of 5 circles \[~(\text{2}\times \text{52}\times \text{73) cm}\] \[=(\text{25}\times \text{7})\text{(2}\times {{\text{5}}^{\text{2}}}\times {{\text{7}}^{\text{3}}}\text{) c}{{\text{m}}^{\text{2}}}\] \[={{\text{2}}^{\text{6}}}\times {{\text{5}}^{\text{2}}}\times {{\text{7}}^{\text{4}}}\text{c}{{\text{m}}^{\text{2}}}\] \[2-\sqrt{4}=2-2=0\] \[{{(\sqrt{5})}^{2}}=5\]Radius of the smallest circle, r = 7 cm.You need to login to perform this action.
