Answer:
Area of a semi circle = 1/2 πr²
Area of a semi circle = 1/2 π(5)² = 25π/2
OP = 10 cm
OQ = 10 cm (radius)
PQ = 5 + 5 = 10 cm
Since all the length are equal, it is an equilateral triangle
Area of an an equilateral triangle = √3/4 (side)²
Area = √3/4 (10)²
It is an equilateral triangle
⇒∠POQ = 60º
Area of the sector = 60/360 x π(10)²
Area = 50π/3
Find the area of the segment PAQ:
Area of the segment = Area of the sector - Area of the triangle
Area = 50π/3 - 25√3
Area = 25(2π/3 - √3)
Find the area of the shaded region:
Area = 25π/2 - 25(2π/3 - √3)
Area = 25(π/2 - 2π/3 + √3)
Area = 25( √3 - π/6) [ Shown ]
From a deck of cards, 10 cards are picked at random and shuffled. The cards are as follows:
6, 5, 3, 9, 7, 6, 4, 2, 8, 2
Find the probability of picking a card having value more than 5 and find the probability of picking a card with an even number on it.
