1.	Find the area of the following
Answer» BASE of the triangle = 8 cm Height of the triangle = 6 cm Area of a triangle = Base × Height Area of the triangle = 8 cm × 6 cm Area of the triangle = 48 SQ.cm . Diameter of the semi-circle = 8 cm Radius of the semi-circle = 8 cm / 2 = 4 cm Area of a semi-circle = 1/2 × πr^2 where, R is the radius. Area of the semi-circle = 1/2 × 3.16 × 4^2 Area of the semi-circle = 25.28 sq.cm Total area of the figure = Area of the triangle + Area of the semi-circle = 48 + 25.28 sq.cm = 73.28 sq. cm The area of the figure is 73.28 sq.cm .

Answer»

BASE of the triangle = 8 cm

Height of the triangle = 6 cm

Area of a triangle = Base × Height

Area of the triangle = 8 cm × 6 cm

Area of the triangle = 48 SQ.cm .

Diameter of the semi-circle = 8 cm

Radius of the semi-circle = 8 cm / 2

= 4 cm

Area of a semi-circle = 1/2 × πr^2

where, R is the radius.

Area of the semi-circle = 1/2 × 3.16 × 4^2

Area of the semi-circle = 25.28 sq.cm

Total area of the figure = Area of the triangle + Area of the semi-circle = 48 + 25.28 sq.cm = 73.28 sq. cm

The area of the figure is 73.28 sq.cm .
