Question

the radius of the sphere whose sueface area is 314cm2
fill in the blanks​

Answer 1

Answer:

surface area=314cm

2

⇒ 4πr

2

=314

⇒ 4×3.14×r

2

=314

⇒ r

2

=

4×3.14

314

=

4×314

314

⇒ r

2

=25

⇒ r=5cm

Answer 2

Radius → 5cm

Step-by-step explanation:

CSA of sphere → 4πr^2

4πr^2 = 314 cm^2

4×3.14×r^2 = 314

4×r^2 = 314/3.14

4r^2 = 100

r^2 = 25

r = 5cm
