A) 4:3
B) 3:4
C) 1:3
D) 3:1
Correct Answer: C
Solution :
Volume of sphere \[c{{m}^{2}}\]and it's surface area\[\frac{25\pi }{3}\]. ratio \[\left( a \right)\text{ }A-\left( s \right),B-\left( r \right),C-\left( p \right),D-\left( q \right)\] But r = 1 unit (unit radius) \[\text{ }A-\left( s \right),B-\left( r \right),C-\left( p \right),D-\left( q \right)\] ratio \[(A)=\sqrt{s(s-a)(s-b)(s-c)},\] or \[s=\frac{a+b+c}{2}.\]
