गोलक का क्षेत्रफल = 4 × π × (r)^2

प्रथम गोलक का क्षेत्रफल = 4×3.14×(21/2)^2

= 4×3.13×(10.5)^2

= 1384.74 cm^2

द्वितीय गोलक का क्षेत्रफल = 4×3.14×(17.5/2)^2

= 4×3.14×(8.75)^2

= 961.625 cm^2

दोनों गोलकों को बनाने में लगी धातु का अनुपात ,

= 1384.74/961.625

= 36/25

अनुपात = 36 : 25 अथवा 1.44 : 1
