Answer 1

Area of given figure = 27.1 unit² (Approx.)

Explanation:

Given:

Radius of hemisphere = 2.7 unit

Height of triangle = 5.8 unit

Number of triangle = 2

Base of triangle = 2.7 unit

Find:

Area of given figure

Computation:

Area of given figure = Area of hemisphere + 2[Area of triangle]

Area of given figure = [(πr²) / 2] + 2[(1/2)(b)(h)]

Area of given figure = [(3.14)(2.7)²) / 2] + 2[(1/2)(2.7)(5.8)]

Area of given figure = [(3.14)(7.29) / 2] + [(2.7)(5.8)]

Area of given figure = [11.44 + 15.66]

Area of given figure = 27.1 unit² (Approx.)
