Question

either enter an exact answer in terms of π or use 3.14 for π and round your final answer to the nearest hundredth. image of a sphere with radius 2 units³

Explanation:

Step1: Identify the radius

The radius $r = 2$.

Step2: Apply volume formula for sphere

Volume $V = \frac{4}{3}\pi r^3 = \frac{4}{3}\pi (2)^3 = \frac{32}{3}\pi$? Wait, no—wait, the figure is a circle with radius 2, but the unit is cubic. Wait, maybe it's a sphere? Wait, the circle with radius 2: if it's a sphere, volume is $\frac{4}{3}\pi r^3$. Wait, $r=2$, so $\frac{4}{3}\pi(8)=\frac{32}{3}\pi≈10.67$? No, wait the original problem—wait the image shows a circle with radius 2, but the input box is units³. Oh, maybe it's a sphere (since volume is cubic). So exact value is $\frac{32}{3}\pi≈10.67$? Wait no, wait maybe I misread: the dashed line is 2, so radius is 2. Sphere volume: $\frac{4}{3}\pi r³ = \frac{4}{3}\pi(8) = \frac{32}{3}\pi ≈10.67$. Or wait, is it a hemisphere? No, the problem says "either exact in terms of π or use 3.14". Wait, maybe the problem is to find the volume of a sphere with radius 2. So exact answer is $\frac{32}{3}\pi$ and approximate is ~10.67. But wait, maybe the figure is a circle (area is $4\pi≈12.57$) but unit is cubic. Oh, maybe the user made a typo, but given the unit is cubic, sphere is likely. Wait, let's confirm: sphere volume formula is $\frac{4}{3}\pi r³$. Radius 2: $\frac{4}{3}\pi*8=\frac{32}{3}\pi≈10.67$. But if it's a cylinder? No, no height given. So most likely sphere. So exact answer is $\frac{32}{3}\pi$ and approximate is 10.67. But wait, the initial thought: maybe the problem was area (circle area $πr²=4π≈12.57$) but unit is cubic. Hmm. But given the input box is units³, sphere is correct. So:

Step1: Note the radius

Radius $r = 2$.

Step2: Calculate sphere volume

$V = \frac{4}{3}\pi r^3 = \frac{4}{3}\pi(2)^3 = \frac{32}{3}\pi$.

Step3: Approximate with π=3.14

$\frac{32}{3}×3.14≈10.67$.

Answer:

$4\pi$ or 12.57
