Question

find the circumference and the area of the circle below.
c= \square m
a= \square m²

Explanation:

Step1: Recall formulas for circle

Circumference \( C = 2\pi r \), Area \( A=\pi r^{2} \), where \( r \) is radius. Given \( r = 10m \).

Step2: Calculate Circumference

Substitute \( r = 10 \) into \( C = 2\pi r \):
\( C = 2\times\pi\times10 = 20\pi \approx 20\times3.14 = 62.8 \) (using \( \pi\approx3.14 \))

Step3: Calculate Area

Substitute \( r = 10 \) into \( A=\pi r^{2} \):
\( A=\pi\times10^{2}=100\pi \approx 100\times3.14 = 314 \) (using \( \pi\approx3.14 \))

Answer:

Circumference \( C = 20\pi \approx 62.8 \) m, Area \( A = 100\pi \approx 314 \) \( m^{2} \) (or keep in terms of \( \pi \): \( C = 20\pi \) m, \( A = 100\pi \) \( m^{2} \))
