The area of a circle with a radius of 26 inches

2,123.7square inches

Step-by-step explanation:

the area of a circle with a radius of 26 inches (diameter of 52 inches)   2,123.7 square inches

Step-by-step explanation:

1. To find the area of a circle with the radius, square the radius, or multiply it by itself.

2. Then, multiply the squared radius by pi, or 3.14, to get the area.

3. To find the area with the diameter, simply divide the diameter by 2, plug it into the radius formula.

4. solve as before.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

answer:

a=9
