Question

4)The measures of a minor are PXQof a circle with centre 0 is 110 degree What is the measure of the major arc PYQ?
5) If the side of a squares is tripled How many times its perimeter will be that of the original square.​

Answer 1

Step-by-step explanation:

4 Suppose PQ is the minor arc and then m(arc PQ) = 110°. We know that, measure of major arc = 360° − measure of corresponding minor arc. Hence, the measure of major arc PYQ is 250°.

5. 3 times

Let the first square have sides of length x meter. If sides get tripled, then the side of the new square will be 3 times the earlier side. We know that the formula of the perimeter of the square is 4×side. Therefore, the perimeter of the new square is 3 times the perimeter of the first square.

Answer 2

Step-by-step explanation:

4) measure of major arc =?, measure of minor arc =110°

measure of minor arc +measure of major arc =360°

110°+measure of major arc PYQ=360°

measure of arc PYQ=360°-110°=250°

therefore the measure of arc PYQ =250°
