Answer:

The correct answer would be a kidney.

A kidney is a bean-shaped organ present in a pair in vertebrates.

The main function of the kidney is the filtration of the blood which leads to the production of urine.

Kidney consists of millions of nephrons (structural and functional unit of a kidney) which help in filtration, reabsorption, secretion, and excretion.

Filtration is the process by which large substances such as proteins, cells et cetera are retained while smaller molecules are filtered which constitute the ultra-filtrate. It takes place at renal corpuscle.

Kidney generates around 180 liters of filtrate in a day out of maximum amount is reabsorbed by other parts of the nephron.

A circle has a radius of 10 inches. Find the approximate length of the arc intersected by a central angle of mc001-1. Jpg 6. 67

Andrei [34K]

The approximate length of the arc intersected by the central angle is 20.94 inches.

The given parameters:

<em>Radius of the circle, r = 10 inches</em>
<em>Central angle, </em> $\theta = \frac{2\pi }{3} \ rad$ <em />

<em />

The approximate length of the arc intersected by the central angle is calculated as follows;

S = rθ

where;

<em>S is the length of the arc</em>

Substitute the given parameters and solve for the length of the arc

$S = 10 \ in \times \frac{2\pi }{3} \\\\S = 20.94 \ inches$

Thus, the approximate length of the arc intersected by the central angle is 20.94 inches.
