Question

the ratio of the raddiie of two spheres is 4:5 . the ratio of their whole surface is - 4:5 , 5:4,2:√5,16:25​

Answer 1

Step-by-step explanation:

The ratio of radii of two spheres is 5:4 .the ratio of their whole surface area ... let the radius of sphere 1 be R and sphere 2 be r ... द्विघात समीकरण 3x²+√8x-16=0 के लिए ,अचर c का ...

Answer 2

Answer:

16:25

Step-by-step explanation:

radius of first sphere = 4R

that of second sphere = 5R

surface area of a sphere is given by 4πR^2

ratio =

4π(4R)^2/4π(5R)^2

= 16:25
