Answer:
The volume of 250 magnets is 625cm³
Step-by-step explanation:
We know that the formula to calculate the volume of a sphere is
v = 3/4 * π * r³
π = 3.14
r = 1.02cm
we replace the values and calculate the volume of a sphere
v = 3/4 * 3.14 * (1.02cm)³
v = 3/4 * 3.14 * 1.061208cm³
v = 2.49914484cm³
to calculate the volume of 250 spheres we simply multiply by 250
250 * 2.49914484cm³ = 624.78621
if we round to the nearest cubic cm
624.78621cm³ = 625cm³
<u>Answer</u>
2/3
<u>Explanation</u>
For f(x) = g(x) we should equate the two functions to get the value of x.
f(x) = g(x)
−3x + 4 = 2
-3x + 4 - 4 = 2 - 4
-3x = -2
Dividing by -3 on both sides;
(-3x)/-3 = (-2)/-3
x = 2/3
