To find mean you add all the values in your data together and divide by the # of values you have.
Answer:
120i
Step-by-step explanation:
;i × i = -1....so hence
4i × (-5i) = -20 i^2...which is -20(-1) = 20....
then you multiply with 6i
20(6i) = 120i
Step-by-step explanation:
area of rrctangle:
12×8= 96cm²
now if rectangle dissapears and then we "glue" what's left, we gonna get two circles
area of circle which gas diameter of 12cm( so radius will be 6cm)will be
πr²=36π≈113.04
another circles radius is 4cm,so area is:
16π≈50.25
sum of all areas: S≈96+113.04+50.25≈259.28cm2
