It would help if you proofread your questions before you posted them. You omitted π.
V = 4/3πr^3 = 4/3 * 3.14 * 4.5 * 4.5 *4.5 = ?
Find the volume of cylinder solid figures applying the steps provide use π=3.14
To find the volume of a sphere using the formula V = (4/3)πr^3, we need to substitute the given radius into the formula.
Given:
Radius (r) = 4.5 inches
π (pi) = 3.14
Substituting these values into the formula, we have:
V = (4/3) * 3.14 * 4.5^3
To calculate this, perform the following steps:
1. Calculate the value of the radius raised to the power of 3:
4.5 * 4.5 * 4.5 = 91.125
2. Multiply the result by 3.14 and the fraction (4/3):
(4/3) * 3.14 * 91.125
3. Evaluate the final expression:
V = 4/3 * 3.14 * 91.125 ≈ 381.6 cubic inches
Therefore, the volume of the given sphere is approximately 381.6 cubic inches.
To find the volume of a sphere, we can use the formula V = (4/3)πr^3, where V represents the volume and r represents the radius of the sphere.
In this case, you're given that the radius (r) is 4.5 inches and π is equal to 3.14.
Now, substitute the values into the formula:
V = (4/3) * 3.14 * (4.5)^3
Simplifying this:
V = (4/3) * 3.14 * 91.125
V = 4.188 * 91.125
V ≈ 380.132 cubic inches
Therefore, the volume of the sphere is approximately 380.132 cubic inches.
