Find the volume of a sphere with radius 9 yd.

A.

3,829.7 yd3

B.

3,052.1 yd3

C.

381.5 yd3

D.

339.1 yd3
the answer is B=3052.1

yes, i agree with you

To find the volume of a sphere, you can use the formula:

V = (4/3) * π * r^3

where V is the volume, π (pi) is a constant approximately equal to 3.14159, and r is the radius of the sphere.

In this case, the radius is given as 9 yd. So, we can substitute this value into the formula:

V = (4/3) * 3.14159 * (9 yd)^3
= (4/3) * 3.14159 * 729 yd^3
= 12.56636 * 729 yd^3
= 9,166.55244 yd^3

Therefore, the volume of the sphere is approximately 9,166.55244 yd^3.

Comparing this to the answer options provided:

A. 3,829.7 yd^3
B. 3,052.1 yd^3
C. 381.5 yd^3
D. 339.1 yd^3

We can see that none of the answer options match the calculated volume of 9,166.55244 yd^3. Therefore, the given answer of B=3,052.1 yd^3 is incorrect.
