Find the area of this semi-circle with diameter, d = 51cm.
Give your answer rounded to 2 DP.

Answer

1021.41

Step-by-step explanation:

area of a circle=πr^2

r=radius=half the diameter

π*(25.5^2)=2042.82

a semi circle is half a circle so you have to half the area to get 1021.41

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

i can not answer the question due to the fact that you spelled "carton" as "cartoon", a cartoon is something you watch on tv, a carton is a box that holds things. and also you've been waiting for this question for a while so why don't you get off your lazy a** and try to figure it out for yourself for once!
