Question

A circular flower garden has a radius of 19 ft that

has to be mulched. Each bag of mulch covers 32square feet. How
many bags of mulch are needed? Use TI = 3.14. Round to the
nearest whole number

Answer 1

Explanation:

`area \: of \: garden = \pi {r}^(2) \\ = 3.14 * {19}^(2) \\ = 1133.54 \: {ft}^(2) \\ number \: of \: bags = (area \: of \: garden)/(area \: covered\: by \: bag) \\ = (1133.54)/(32) \\ = 36 \: bags`
