Answer: Volume = 972\pi units^{3}

Explanation: To find the volume of a sphere, first start with the formula for the volume of a sphere.

Volume = \frac{4}{3} \pi r^{3}

The sphere has a radius of 9 units, so we can plug 9 into the formula.

Volume = (\frac{4}{3}) (\pi) (9units)^{3}

Now, let's simplify the exponent. Remember that 9³ is equal to 9 units x 9 units x 9 units or 729 units³.

Volume = (\frac{4}{3}) (729units^{3}) (\pi)

Notice that we can cross cancel 3 in \frac{4}{3} and 729 to 1 and 243.

Volume = (4) (243 units^{3}) (\pi)

Volume = 972\pi units^{3}

The correct statement is that the concentration of acetylcholine will be inhibited by enzymes and can cause several diseases as follows:

  • Alzheimer's disease-related to damage to brain cells,
  • memory loss,
  • and thinking ability.

How to reduce the symptoms of these diseases is to use drugs that contain cholinesterase inhibitors.

<h2>Further Explanation </h2>

Acetylcholine is a neurotransmitter that plays an important role in the functioning of the autonomic nervous system. Acetylcholine is one of the most commonly recognized neurotransmitters or nerve stimulating chemicals. These neurotransmitter compounds can be found in the nervous system.

There are several side effects of the acetylcholine drug, which are as follows:

  • Can cause a lot of sweat
  • Excessive salivation
  • Stomach ache
  • Headache
  • Blood vessel dilation
