Question 1.
In figure, ABCD is a square of side 14 cm. Semi-circles are drawn with each side of square as diameter. Find the area of the shaded region.
Areas Related to Circles Class 10 Maths CBSE Important Questions With Solutions 1
Solution:
Area of the square ABCD = 14 x 14 = 196 cm²
Area of semicircle AOB=1/2 x πr²
=1/2×22/7x7x7
Similarly, area of semicircle DOC = 77 cm²
Hence, the area of shaded region (Part W and Part Y) = Area of square -Area of two semicircles AOB and COD
= 196 – 154 = 42 cm²
Therefore, area of four shaded parts (i.e. X, Y, W, Z) = (2 x 42) cm² = 84 cm²

Question 2.
In figure, are shown two arcs PAQ and PBQ. Arc PAQ is a part of circle with centre O and radius OP while arc PBQ is a semicircle drawn on PQ as diameter with centre M. If OP = PQ = 10 cm, show that area of shaded region is
25(√3- π /6)cm²
Areas Related to Circles Class 10 Maths CBSE Important Questions With Solutions 2
Solution:
OP = OQ = 10 cm
PQ = 10 cm
So, ΔOPQ is an equilateral triangle
∠POQ = 60°
Area of segment PAQM = Area of sector OPAQ – Area of ΔOPQ
=60/360 x π x 10 x 10-√3/4 x 10 x 10
=(100π/6-100√3/4)cm²
Area of semicircle =1/2 x π x 5 x 5 = 25/2π cm²
Area of the shaded region =25/2π-(100π/6-100√3/4)=25π/2-50π/3+25√3
=75π-100π/6+25√3=25√3-25π/6
=25(√3-π/6)cm²

Question 3.
In figure, O is the centre of a circle such that diameter AB = 13 cm and AC = 12 cm. BC is joined. Find the area of the shaded region.
Areas Related to Circles Class 10 Maths CBSE Important Questions With Solutions 3
Solution:
Here, BC² = AB²-AC²
= 169-144 = 25 BC = 5
Area of shaded region = Area of semicircle – Area of right triangle ABC
=1/2 x πr²-1/2AC x BC
=1/2 x 3.14(13/2)²-1/2 x 12 x 5
=66.33 – 30 = 36.33 cm²

Question 4.
In figure, find the area of the shaded region, enclosed between two concentric circles of radii 7 cm and 14 cm where∠AOC = 40°.
Areas Related to Circles Class 10 Maths CBSE Important Questions With Solutions 4
Solution:
Area of shaded region=360°-θ/360° x π(R²-r²)
=320°/360° x π[(14)²-(7)²]
=8/9 x 22/7(196-49)=8/9 x 22/7 x 147
=1232/3=410.67 cm²

Question 5.
Find the area of shaded region in figure, where a circle of radius 6 cm has been drawn with vertex O of an equilateral triangle OAB of side 12 cm
Areas Related to Circles Class 10 Maths CBSE Important Questions With Solutions 5
Solution:
Area of  ΔOAB=√3/4(side)²=√3/4 x (12)²
=36√3=36 x 1.73
=62.28 cm²
area of circle with center O =πr²=3.14 x (6)²
=3.14 x 36 =113.04 cm²
area of sector(OLQP)=πr² x θ/360°=3.14 x 6² x 60°/360°
=3.14 x 36 x 1/6 =18.84 cm²
area of shaded region=area of ΔOAB+area of circle-2 area of sector OLQP
=(62.28+113.04-2 x 18.84)cm²
=137.64cm²

Question 6.
In figure, is a chord AB of a circle, with centre O and radius 10 cm, that subtends a right angle at the centre of the circle. Find the area of the minor segment AQBP. Hence, find the area of major segment ALBQA
Areas Related to Circles Class 10 Maths CBSE Important Questions With Solutions 6
Solution:
Area of minor segment APBQ=θ/360° x πr²-r²sin45°cos45°
=3.14 x 100/4-100 x 1/√2 x 1/√2
=(78.5-50)cm²=28.5 cm²
Area of major segment ALBQA =πr²-area of minor segment
=3.14 x (10)²-28.5
=(314-28.5)cm²=285.5 cm²
