Question

the surface area of a sphere is 448 cm2 find its radius​

Answer 1

$\bf\huge\underline{\underline{ Given :- }}$

• Surface area of sphere is 448 cm²

$\bf\huge\underline{\underline{ To \: Find:- }}$

• Radius

$\bf\huge\underline{\underline{ Answer :- }}$

• $\boxed{\bf\red{A = 4πr²}}$

• 4 πr² = 448

• r² = $\frac{448}{4π}$

• r = $\sqrt{35.6}$

• r = 5.9 ≈ 6 cm

$\rule{15cm}{0.02cm}$
