Question

Urgent please help..

Answer 1

0.39

Explanation:

Height of triangle (h) = 2.5 + 4 = 6. 5 cm

Base of triangle (b) = 3 + 3 = 6 cm

Radius of circle (r) = 4 cm

Required probability = Area of triangle/Area of circle

`= \frac{ (1)/(2) bh }{\pi {r}^(2) } \\ \\ = \frac{ (1)/(2) * 6 * 6.5 }{3.14 * {4}^(2) } \\ \\ = (3 * 6.5)/(3.14 * 16) \\ \\ = (19.5)/(50.24) \\ \\ = 0.388136943 \\ \\ \approx0.39`
