Answer:
V=25.133 cm^3
(Is 4 the diameter you were given? To get one of those answers, I think you May have put the wrong diameter)
Explanation:
Radius is diameter/2
R=4/2
R=2
Volume of a sphere=4/3πr3
V=4/3π(2)3
V=25.133 cm^3
Answer:
exponents
Explanation:
The exponents in scientific notation should be added when multiplying, and subtracted when dividing. The exponents need to be the same so the leading numbers can be multiplied or divided. The result has the same number of decimal places as the least precise number.

Answer:
5.89 g × 10⁶ μg
Explanation:
Step 1: Convert 5.00 scruples to grains
We will use the conversion factor 1 scruple = 20 grains.
5.00 scruple × 20 grain/1 scruple = 100 grain
Step 2: Convert 100 grains to ounces
We will use the conversion factor 1 oz = 480 grains.
100 grain × 1 oz/480 grain = 0.208 oz
Step 3: Convert 0.208 oz to grams
We will use the conversion factor 1 oz = 28.34 g.
0.208 oz × 28.34 g/1 oz = 5.89 g
Step 4: Convert 5.89 g to micrograms
We will use the conversion factor 1 g = 10⁶ μg.
5.89 g × 10⁶ μg/1 g = 5.89 g × 10⁶ μg
