Answer: I assume you mean surface area of a sphere.
The formula is 4πr²
If radius=3, then:
4 times
times 3²
4 times
times 9
= 113.142857
Rounded to 1 decimal place = 113.1
<u>NOTE: In place of π you can also use 3.14.</u>
The pitcher can throw 58 until he reaches the limit, hopefully I helped :)
Step-by-step explanation:
slope = Change of y/ change of x
= 4/4
= 1
slope + or > 0 y increases when x increases
Circumference = diameter * pi
using 3.14 for pi
diameter = 25.12/3.14 = 8 yards
radius = diameter/2 = 8/2 = 4
radius = 4 yards
