Find the arc length of the partial circle. Either in an exact answer in terms of 3.14 for pi and enter your answer as a decimal.

Given:

From the given figure, the radius of the partial circle is 7 units.

The central angle is 90°

We need to determine the arc length of the partial circle.

Arc length:

The arc length of the partial circle can be determined using the formula,

Substituting , π = 3.14 and r = 7, we get;

Simplifying, we get;

Dividing, we get;

Thus, the arc length of the partial circle is 10.99 units.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
