Write a program to calculate the (i) area, (ii) ZA and ZC of the triangle shown below. Formulas: Area: a+b+c (a) Area = s(sa)(sb)(sc) where s = 2 Area = 9.4049 Angles: (b) ZA= cos -1 1 b² + c²_a²) 2bc a = 75.4844 (c) ZC = sin-1 csinB b C = 25.2304 A c = 2.9 m b = 6.7 m 80° B a = 6.6 m 2. Calculate the area and circumference of a circle of diameter 10 cm. Formulas: Area = r² and circumference = 2лr where r is the radium of the circle. Ans) area = 78.5398 Ans) circumferences=2*pi*r 31.4159 1
