Answer:
9.5 inches
Step-by-step explanation:
The relationship is presumed to be ...
(first week's growth) + (second week's growth) = (growth in two weeks)
(first week's growth) + 3.43 inches = 12.93 inches . . . . . fill in the numbers
Subtract 3.43 from both sides of the equation:
first week's growth = 12.93 inches - 3.43 inches
first week's growth = 9.50 inches
The plant grew 9.50 inches in the first week.
Answer: (12,2480),(−1,−380)
Step-by-step explanation:
1. To solve this problem, you must aplpy the formula for calculate the volume of a sphere, which is:
V=4/3(πr)
V is the volume of the sphere.
r is the radius of the sphere.
2. You must calculate the radiius. You have that the beach <span>ball has a diameter of 18 inches, then:
r=diametert/2
r=18 inches/2
r=9 inches
3. When you substitute r= 9 inches into the formula, you obtain:

V=4/3(πr)
V=3053.62 inches</span>³
