A composite figure has a radius of 10 cm

Given:

The radius of the circle is 10 cm

The central angle of the circle is (360 - 90)° = 270°

We need to determine the area of the composite figure.

Area of the composite figure:

The area of the figure can be determined using the area of the sector formula.

Thus, we have;

Substituting and in the above formula, we get;

Simplifying, we get;

Multiplying, we get;

Dividing the terms, we get;

Thus, the area of the composite figure is 235.5 cm²

Hence, Option C is the correct answer.

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
