Question : If ‘r’ is the radius of a circle, then it's circumference is given by 
a. 2πr
b. None of these
c. πr
d.2πd
 
Answer : A
Explanation: If the radius of a circle is given, the circumference or perimeter can be calculated using the formula below:-
Circumference = 2πr
 
Question : The perimeter of a protractor is 
a.πr
b.πr+2r 
c.π+r
d.π+2r
 
Answer : B
Explanation: Let radius of the protractor be r ∴Perimeter of protractor = Perimeter of semicircle + Diameter of semicircle 
=>Perimeter of protractor = πr+2r

Question : The angle described by the minute hand between 4.00 pm and 4.25 pm is 
a. 900
b. 1500
c. 1250
d. 1000

Answer : B
Explanation: Time duration between 4.00 pm and 4.25 pm = 25 minutes
Angle described by minute hand in 60 minutes =360 0 
Angle described by minute hand in 25 minutes =360 0/600×25=1500

Question : A chord of a circle of radius 10cm subtends a right angle at the centre.find
(1) area of the minor sector (2) area of the minor segment
(2) area of the major sector (4) area of the major segment
Answer : 
78.5, 28.5, 235.5, 285.5

Question : What is the perimeter of a square which circumscribes a circle of radius a cm? 
Answer : When a square circumscribes a circle, the radius of the circle is half the length of the square.
Therefore, if the radius of the circumscribed circle is a, the diameter will be 2a. It is this diameter that is equal to the length of the square.
Therefore, the length of the square is 2a cm.
Then area of a square =4 length
= 4 2a cm
= 8a cm 
 
Question : On a square cardboard sheet of area 784 cm2, four circular plates of maximum size are placed such that each circular plate touches the other two plates and each side of the square sheet is tangent to circular plates. Find the area of the square sheet not covered by the circular plates. 
Answer : Let the radius of each circular plate be r cm. Then,
WT_Areas related to circles test 2
Length of each side of the square sheet = 4r cm. 
∴Area of the square cardboard sheet = (4r 4r) cm2 = 16 r2 cm2 
But, the area of the cardboard sheet is given to be 784 cm2 
16r2 = 784 r2 = 49 
r = 7 
Area of one circular plate = = 154 cm 
Area of four circular plates = 4× 154 cm2 = 616 cm
Uncovered area of the square sheet = (784 - 616) cm2 = 168 cm2
