Which table represents a direct variation function?(NEEDED ANSWER ASAP)
1 answer:
Answer:
See attachment
Step-by-step explanation:
The table that represent a direct variation is shown in the attachment.
To determine a direct variation from tables, you need to inspect the y-intercept of each table.
If there is a table with y-intercept of 0, then it represents a direct variation.
Or you could check the table with equation of the form: if you cannot see zero in the y-intercepts directly

Given that, a sphere has a surface area of about 999 square millimeters.
Formula to find the surface area of sphere is,
S= 4πr² Where r = radius of the sphere and S= surface area.
Given S= 999 square millimeters.
So, we can write:
4πr² = 999
4 * 3.14 * r² = 999 Since, π = 3.14
12.56 *r² = 999
Divide each sides by 12.56.
r² = 79.53821656
r = √79.53821656 Taking square root to each sides of equation.
r = 8.918420071
So, r = 8.918 Rounded to nearest thousandth.
So, radius of the sphere is 8.918 millimeters.
Hope this helps you!
