Area of a circle, diameter = 16.8cm

221.56 cm^2 or 70.56pi

Step-by-step explanation:

Area of a circle  = pi*radius^2

Radius = diameter/2, radius = 8.4

3.14(8.4)^2 = 221.56 cm squared, or 70.56pi

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

answer is d-29

step-by-step explanation:

since you didn't include the picture, i can give you the description so you know how to pick the correct answer. the third quartile of a data is always shown in a box plot. in the middle of your graph should be a box. the third quartile is the value that goes with the far right edge of the box.
