Which measurement is closest to the area on the figure? and show work,
a. 32.1 cm c. 51.8 cm
b. 39.3 cm d.55.4 cm

Area of the circle = πr²
2 quarter circles give one half circle, area of the half circle =πr²/2=(π*5²)/2
Area of the right triangle = 1/2*b*h, but here base and height are equal , so we can write for area of the triangle 5*5/2 =25/2

All area= (π*5²)/2 + 25/2≈51.8 cm²
Answer is C

Technically speaking, histograms are another version of bar charts, if you need to work one out then skim through google hope-o that -o!
