22. Find the radius of a sphere with a volume of 33.5 ��3. Use =3.14 and
round your answer to the nearest whole. Formula: V= 43��3
O. 2 m
P. 8 m
Q. 14 m
To find the radius of a sphere, we can use the formula V = (4/3)πr^3, where V is the volume of the sphere and r is the radius.
Given that the volume of the sphere is 33.5 m³, we can substitute V = 33.5 m³ into the formula:
33.5 = (4/3)πr^3
To solve for r, divide both sides of the equation by (4/3)π:
r^3 = (33.5 * 3) / (4 * π)
r^3 = 100.5 / π
r^3 ≈ 32.03
To find the value of r, take the cube root of both sides of the equation:
r ≈ ∛(32.03)
Using a calculator, we find that r ≈ 3.09
Rounding to the nearest whole number, the radius of the sphere is 3. Therefore, the correct answer is nowhere among the options (O, P, or Q) provided.
the answer is o but explain why
Apologies for the confusion in my previous response. Let's recalculate using the correct formula for the volume of a sphere.
The formula for the volume of a sphere is V = (4/3)πr^3, where V is the volume and r is the radius.
Given that the volume of the sphere is 33.5 m³, we can substitute V = 33.5 m³ into the formula:
33.5 = (4/3)πr^3
To solve for r, we can rearrange the equation:
r^3 = (3/4π) * 33.5
r^3 ≈ 10.04
To find the value of r, take the cube root of both sides of the equation:
r ≈ ∛10.04
Using a calculator, we find that r ≈ 2.15
Rounding to the nearest whole number, the radius of the sphere is 2. Therefore, the correct answer is option O, 2 m.
