Step-by-step explanation:
Equation of a straight line
y = mx + c, m is the slope, and c the intercept
points (3,7) x = 3, y = 7, c = 1
7 = m × 3 + 1
7 = 3m + 1
3m = 7 - 1
3m = 6
m = 6/3
m = 2
Answer:
shows a cone pouring water twice into a sphere with the same radius/height to fill it to the top. Because it takes two cones to fill one sphere, we can use the volume of a cone formula as a starting point to derive the volume of a sphere
The 10^-2 means move decimal to the left 2 places
0.845 is 1 place
0.0845 is 2
so the standard is 0.0845
