Answer:

The exact value of its surface area = 144π m²

The exact value of its volume = 288π m³

Step-by-step explanation:

∵ The diameter of the sphere is 12m

∴ The radius of the sphere = 12 ÷ 2 = 6m

∵ The surface area of the sphere = 4πr²

∴ The surface area = 4 × π × 6² = 144π m²

∵ The volume of the sphere = 4/3 πr³

∴ The volume = \frac{4}{3}\pi (6)^{3} = 288π m³

tester [92]

Answer:

\%Percent = 17.14\%

Step-by-step explanation:

Given

Carbohydrate = 250\ g

Protein = 60\ g

Fat = 40\ g

Required

Determine the percentage of protein

First, we need to calculate the total:

Total = Carbohydrate + Protein + Fats

Total = 250\ g + 60\ g + 40\ g

Total = 350\ g

Percentage of protein is calculated as thus:

\%Percent = \frac{Protein * 100\%}{Total}

\%Percent = \frac{60 * 100\%}{350}

\%Percent = \frac{6000\%}{350}

\%Percent = 17.14\%
