Answer: I assume you mean surface area of a sphere.
The formula is 4πr²
If radius=3, then:
4 times [tex]\frac{22}{7}[/tex] times 3²
4 times [tex]\frac{22}{7}[/tex] times 9
= 113.142857
Rounded to 1 decimal place = 113.1
NOTE: In place of π you can also use 3.14.
Answer:
113.1 units²
Step-by-step explanation:
Surface area of sphere = 4×pi×r²
= 4 × pi × 3²
= 36pi units²
= 113.0973355 units²
= 113.1 units²
