Your answer should be 81 for a. I got this result by multiplying 9 by 9.
A <u>radius</u> and <u>diameter</u> are <em>parts</em> of a circle. Thus the reasons required in the question are given as;
i. A<u> tangent</u> is always <em>perpendicular</em> to the radius of a circle because they are always at a <u>right</u> angle.
ii. A line that is drawn from the <em>end</em> of a <u>diameter</u> of a circle to its <em>circumference</em> form a <u>right</u> angle because they are always <em>perpendicular</em>.
A <em>circle </em>is a figure that is bounded by a <em>curved </em>line which is called its <u>circumference</u>. Some of its parts are radius, diameter, chord, sector, etc.
- A <u>diameter</u> is a line from one point on the <em>circumference</em> of a circle to another through its <em>center</em>.
- A <u>radius</u> is a line drawn from the <em>center</em> of a circle to its <em>circumference</em>. Thus a radius is half of the diameter.
- A <u>tangent</u> is an external line drawn to meet the <em>circumference</em> of a circle at a point,
Thus the <u>reasons</u> required in the question are given as;
i. A <u>tangent</u> is always <em>perpendicular</em> to the <u>radius</u> of a circle because they are always at a right angle.
ii. A <u>line</u> that is drawn from the end of a <em>diameter </em>of a circle to its <u>circumference</u> form a <em>right</em> angle because they are always <em>perpendicular</em>.
