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>
Answer:
p > 220
Explanation:
This inequality says, "p (the weight of the pig) is less than 220." This describes the situation shown. So, the answer is p > 220.
Good luck ^^
Substitute y with 3
7x + 2(3) = 48
7x + 6= 48
Minus 6 over
7x = 42
X= 6
Hope this helps!
So to do this, we take any 2 coordinate points and subtract them to find the slope. For this one i'll go ahead and and take (4,6) and (-2,1), then we set them up. Subtract the X coordinates from each other and the Y's from each other.
4-(-2) change the two negatives to 4+2=6
6-1=5
So 6/5 is the slope, now lets simplify to get 6/5.
Your equation is y=6/5x+3
-Seth.
P.S. It may be y=6/5x+2.5 or something, i cant tell exactly where it goes through the y intercept.
X = 15
Perimeter of a rectangle is 2(l+w) = 2 ( 15+15) = 2 (30)
