CotA = 8/15 = b/p. So, b= 8 and p = 15 . Now by Pythagoras theorem, we get, h = 17 . We know that cosecA = h/p. So, now put the value of h and p, we get, cosecA = 17/15.

ANSWER

Find the area of minor segment of a circle of radius 42cm square If the lenght of corresponding arc is 44cm square

Posted by Tanu Singh 6 years, 4 months ago

CBSE > Class 10 > Mathematics

4 answers

Aadya Singh ? 6 years, 4 months ago

Length of minor arc = 42 => (2πr× thita)/360 = 42 => (2π×44 × thita )/360 = 42 => thita = (42× 360)/ (2π × 44) => thita = 60° . Area of minor segment = (πr^2×thita/360) - 1/2(r^2 sin thita) .Now, put the value of thita and radius, you will get the answer (924 - 441/√3) cm square.
