To find the perimeter of this blue figure, add together the shown lengths of the six sides.
The three measurements on the top have the LCD 4, so we combine 14 3/4, 4 2/4 and 8 2/4. The sum is 26 7/4, or 27 3/4, or 27.75.
The three measurements on the bottom share the LCD 5, so we can immediately combine them, obtaining 32 8/5, or 33 3/5, or 33.60.
Combining 27.75 and 33.60 results in 61.35, or 61 35/100, or 61 7/20.
The perimeter of the given figure is 61 7/20.
C, sorry if its not the correct answer, but I believe it is C
18. 26
19. 10
20. (26×26×26)×(10×10×10) = 17576000
21. (26×26×26) × (1×10×10) = 1757600
22. (26×25×24)+(10×9×8) =11232000
23. (25×24×1)×(10×9×8) =432000
24. 3/6 × 2/13 = 1/13
Answer:
false
Step-by-step explanation:
the formula for the area of a circle is πr^2
π=3.14
r= 1/2 of diameter = 6
3.14 x 6^2
