2p + 4r <===
Answer:
READ VERY CAREFULLY
Step-by-step explanation:
Relate area to the operations of multiplication and addition. a Find the area of a rectangle with whole-number side lengths by tiling it, and show that the area is the same as would be found by multiplying the side lengths
Multiply side lengths to find areas of rectangles with whole-number side lengths in the context of solving real world and mathematical problems, and represent whole-number products as rectangular areas in mathematical reasoning.
Use tiling to show in a concrete case that the area of a rectangle with whole-number side lengths a and b+c is the sum of a×b and a×c. Use area models to represent the distributive property in mathematical reasoning.
Recognize area as additive. Find areas of rectilinear figures by decomposing them into non-overlapping rectangles and adding the areas of the non-overlapping parts, applying this technique to solve real world problems.
To find the top and bottom circles you use:
2(pi x r^2)
- your r (radius) is half of the diameter so 3.
To find the part around it you use:
2 x pi x r x height
Circles: 2(pi x 3^2) = 56.5487
Rectangular around: 2 x pi x 3 x 5 = 94.2478
- then add them together
56.5487 + 94.2478 = 150.7965 yards^2
Answer:
3+7x
Step-by-step explanation:
-We add the number of widgets produced in 3 days to the number originally owned:
#We the determine the widgets destroyed in 3 days:
#Subtract the widgets destroyed from the total owned to get what is left after 3 days:
Hence, the number of widgets remaining after 3 days is 3+7x
