Landon used a semicirce, a rectangle, and a right triangle to form the figure shown.
6 cm
4 cm
- 10 cm
Which is the best estimate of the area of the figure in square centimeters?
A S2 cm
B 44 cm
C 26 cm
D 38 cm
Area of triangle= 0.5 base x height We have the height but we don’t have the base, to calculate the base we subtract 10-6 which equals to 4 0.5 x 4 x4 =8
Area of a semicircle= o.5 x pi x r^2 We have the diameter and to find the radius we divide it by 2 4/2 = 2 0.5 x pi(or 3.14) x 2^2 =6.28 Total area = 24 + 8+ 6.28 =38.28cm^2
