Given that the volume is 3680 cm³, find radius:
[tex]\text { Formula for volume of a sphere =} \dfrac{4}{3} \pi r^3[/tex]
[tex]\dfrac{4}{3} \pi r^3 = 3680
[/tex]
[tex] r^3 = 3680 \div \dfrac{4 \pi }{3} [/tex]
[tex] r^3 = 3680 \times \dfrac{3}{4 \pi } [/tex]
[tex] r^3 = \dfrac{2760}{\pi } [/tex]
[tex]r = 9.58 \text { cm (Nearest hundredth)}[/tex]
With radius, find surface area:
[tex]\text {Surface area = } 4 \pi r^{2} [/tex]
[tex]\text {Surface area = } 4 \pi (9.58)^{2} [/tex]
[tex]\text {Surface area = } 1153.30 \text { cm (Nearest hundredth)}[/tex]
