Answer:
26.13
Explanation:
to find the area of a circle, it's pi*r squared:
pi*3squared=9pi
it's a semi-circle so you divide it by two=4.5pi
they are telling us to use 3.14 instead of pi, so it would be:
4.5*3.14=14.13
now we find the area of the triangle. And we use the formula, (height*base)/2:
6*4/2=12
now we add the sums together, which is:
12+14.13=26.13
