Question

radius of sphere whose surface area is 314cm³​

Answer 1

The radius of the given sphere is 25 cm

Step-by-step explanation:

Total surface area of sphere = 4 \pi r^24πr

We are given that surface area is 314 square CM

$So, 4 \pi r = 3144πr=314$

$4 \times 3.14 \times r = 3144×3.14×r=314$

$r = \frac{314}{4 \times 3.14}$

r = 25 cm

Hence The radius of the given sphere is 25 cm

Answer 2

Answer:

let r cm be the radius of the sphere whose surface area =314cm²

=4 PIEr²= 314

= 4×3.14× r = 314

=r²= 314/4× 3.14=314/4×314

=r²= 25
