Question

What is the area of the circle in terms of
`\pi`?

a. 3.4225
`\pi` m²
b. 6.845
`\pi` m²
c. 7.4
`\pi` m²
d. 13.69
`\pi` m²

Answer 1

`\sf \: d \: = 3.7m \\ \sf \: r \: = (3.7)/(2) = 1.85 \: m\\ \\ \sf \: c \: = \pi {r}^(2) \\ \\ \sf \: c \: = \pi ({1.85})^(2) \\ \sf c = 1.85 * 1.85 * \pi \\ \sf \: c = \boxed {\underline{ \bf a. \: 3.4225\pi \: m ^(2) }}`
