The diagonals of two squares are in the ratio of 2 : 5. Find the ratio of their areas.
Let the diagonals of the squares be 2x and 5x respectively.Ratio of their areas = 12*2x2:12*5x2=4:25
A, B and C are three points on a circle such that the angles subtended by the chord AB and AC at the centre O are 110 and 130 deg, respectively. Then the value of angle BAC is:
In ABC, MN BC, the area of quadrilateral MBCN=130 sqcm. If AN : NC = 4 : 5, then the area of MAN is:
The radius of a circular garden is 42 m. The distance (in m) covered by running 8 rounds around it, is:
Two chords AB and CD of a circle when produced, meet at a point P outside the circle. If AB = 6 cm, PB = 5 cm, PD = 4 cm, then CD is equalto:
In ABC, AD is a median and is a point on AD such that AP : PD = 3 : 4. Then ar( BPD) : ar( ABC)is equal to:
The arc ABC of a circle with centre O subtends 132 at the centre. The chord AB is extended to the point P. The angle CBP is equal to
In a circle of radius 13 cm, a chord is at a distance of 5cm from its center. What is the length of the chord?
In ABC,P is a point on BC such that BP : PC = 3 : 4 and Q is the midpoint of AP. Then ar( ABQ): ar( ABC) is equal to:
