Maharashtra Board 7th Maths Chapter 11, Class 7 Maths Chapter 11 solutions

Question 1.
Choose the correct option.
If arc AXB and arc AYB are corresponding arcs and m(arc AXB) = 120° then m(arc AYB) =
(A) 140°
(B) 60°
(C) 240°
(D) 160°
Solution:
(C) 240°

Hint:
Measure of major arc = 360° – measure of corresponding minor arc
∴ m (arc AYB) = 360 – m (arc AXB)
∴ m (arc AYB) = 360 – 120
∴ m (arc AYB) = 240°

Question 2.
Some arcs are shown in the circle with centre ‘O’ Write the names of the minor arcs, major arcs and semicircular arcs from among them.

Semicircular arcs : arc QPR, arc QYR.

Question 3.
In a circle with centre O, the measure of a minor arc is 110°. What is the measure of the major arc PYQ?
Maharashtra Board Class 7 Maths Solutions Chapter 11 Circle Practice Set 43 2
Solution:
Measure of major arc = 360° – measure of corresponding minor arc
∴ m (arc PYQ) = 360 – 110
∴ m (arc PYQ) = 250°
∴ The measure of the major arc PYQ is 250°.
