Question

find the area of the combined figure given formed by joining a semi circle of diameter 6 cm with the triangle of base 6 cm and height 9 CM use Pi is equal to 3.14​

Answer 1

Answer:

Step-by-step explanation:

find the area of the combined figure given formed by joining a semi circle of diameter 6 cm with the triangle of base 6 cm and height 9 CM use Pi is equal to 3.14​

As fig is not given :

Case 1 : Height 9 = Triangle + Semi circle

Diameter = 6 cm

Radius = 3 cm

Area of semicircle = (1/2)πr² = (1/2)(3.14) & 3² = 14.13 cm²

Triangle height = 9 - (6/2) = 9 - 3 = 6 cm

Area of triangle = (1/2) * 6 * 6 = 18 cm²

Total Area = 14.13 + 18 = 32.13 cm²

Case 2 :Height 9 is of  Triangle only

Area of semicircle = (1/2)πr² = (1/2)(3.14) & 3² = 14.13 cm²

Area of triangle = (1/2) * 6 * 9 = 27 cm²

Total Area = 14.13 + 27 = 41.13 cm²
