Let we asume that √3 is rational i.e it can be qritten as a/b. √3=a/b(where a and b are co prime ). squaring on both sides. (√3)square=(a/b) square. 3= a square/b square. 3b square=a square______(1). 3 divides a square so 3 divides a also. a=3c_____________(2). from 1 and 2 equation. 3c square=3b square 3c square=b square. __________(3) 3divides b square so 3 divides b also. from 2 and 3 wquation it is proved that 3 is a common factor of a and b,which is a contradiction of our assumption this is due ti our wrong assumption .Si √3 is irrational number

Gaurav Seth 6 years, 4 months ago

This statement is false because
CONGRUENT SHAPES are figures with the same size and shape. The lengths of the sides and the measures of the angles are identical. They're exact copies, even if one is oriented differently.
SIMILAR SHAPES are figures with the same shape but not always the same size.

The height of a solid cylinder is 10cm and diameter 8cm , 2 equal conicnal holes have been diameter is 6cm is made from both ends . Find the volume of remaining solid and also its surface area

Posted by Kumbar Bidar 6 years, 4 months ago

CBSE > Class 10 > Mathematics

3 answers

Gaurav Seth 6 years, 4 months ago

Volume of cylinder = π( 4)² ×10

= 160π cm³

volume of one cone = 1/3 × π × 3² ×4
= 12π cm ³

therefore,
volume of both cones = 24π cm³

therefore,

volume of remaining portion = 160π - 24 π

= 136π cm ³
