I can't speak to the cactus specifically, but any sphere has a surface area of

and a volume of

, so the area-to-volume ratio wold be


Where <em>r</em> is the radius of the sphere.
Answer is 90% of 1.
90÷100×1=0.9
Answer:
A) f(x) = 6x + 14
Step-by-step explanation:
6(1) + 14 = 20
6 + 14 = 20
6(1.5) + 14 = 23
9 + 14 = 23
6(2) + 14 = 26
12 + 14 = 26
and so on...

Answer:
1/250 W/m² or 0.004 W/m² or 4 mW/m²
Step-by-step explanation:
The cargo worker is (50 m)/(1 m) = 50 times the reference distance. The intensity varies as the inverse of the square of the distance, so will be ...
(1/50)²×(10 W/m²) = 10/2500 W/m² = 1/250 W/m²
This might be more conveniently written as 4 mW/m².
