Answer:
Option 3. (2π + 40) mm².
Step-by-step explanation:
Area of the composite figure = area of MKCD + area of ABCD + area of semi circle with AB as diameter.
Then Area A = (DC + MK)/2 × DN + AB² + (1/2)×π×2²
= (4 + 8)/2 × 4 + 4² + (1/2)×π×4
= 24 + 16 + 2π = (2π + 40) mm²
Therefore option 3. (2π + 40) mm².
O.o that so hard but my big sister know how to do it
I won't give you the answer because I am sure you are capable of finding it yourself once given a push, but what I would do is simplify all of the numbers into a mixed fraction (a b/c) and then go from there. Don't subtract the two numbers with the denominator of 25 first because they goes against PEMDAS. Change all of the fractions so they have like denominators, and once you solve it, just write the fraction part of the answer (b/c). If you have any other questions, just ask.
m = 5/27
Step-by-step explanation:
y = m+3x.
If y = 5 and x = 9. Then,
5 = m+3(9)
5= m+27.
m = 5/27.
