To solve this completion exercise, you must keep on mind the following information:
- The formula for calculate the area of a sphere, is the following:
Vsphere=4πr³/3
Where Vsphere is the volume of the sphere and "r" is the radius of the sphere.
- Therefore, if you multiply the radius by 3, or triple the radius, the surface area increase by a factor of 9 (3^2=9).
The answer is: T<span>ripling the radius of a sphere increases the surface area by a factor of 9.</span>
Answer:
See below
Step-by-step explanation:
Make <u>SEVEN</u> jumps that are each <u>0.2</u> unit long. You end at <u>1.4</u> which is th product
Add 1/4a to both sides
-4= 8/4a-3
Simplify
-4=2a-3
Add 3 to both sides
-1=2a
Divide both sides by 2
-1/2=a
Final answer: a=-1/2
Step-by-step explanation:
that means
z = k×x×y
4 = k×2×3 = k×6
k = 4/6 = 2/3
so, when x = -6 and y = 2, we get
z = 2/3 × -6 × 2 = 2 × -2 × 2 = -8
