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.
