Transcribed Image Text:
A tree was planted along a sidewalk. This was fine when the tree was a sapling, but is not so good now that the tree has grown (and the roots are starting to damage the surrounding path). 1a) The tree has a (roughly) circular trunk, with a circumference of 38 inches. What is the cross-sectional area of the trunk? You may use 3.14 for pi, and you may round your answer to the nearest square inch. 1b) The tree is in a rectangular planter 3 feet long and 2 feet wide. The city wants to fill the planter with bark chips (mostly to distract from the big root structure). What is the surface area they need to cover with bark chips? This would be the area of the planter, but not counting the cross-sectional area of the tree. Please give your answer in square inches. The following formulas may be helpful: C= 2πr, A = ², and A = lw A tree was planted along a sidewalk.
