1 . Luas =

$\pi \: \times r ^{2}$

$= 3.14 \times 4 \times 4$

$= 50.24 \: cm {}^{2}$

Keliling =

$2 \times \pi \times r$

$= 2 \times 3.14 \times 4$

$= 25.12 \: cm$

2.Luas =

$\pi \times r ^{2}$

$= 3.14 \times 20 \times 20$

$= 1.256 \: cm {}^{2}$

Keliling =

$2 \times \pi \times r$

$= 2 \times 3.14 \times 20$

$= 125.6 \: cm$

3.Volume Tabung =

$\pi \times r {}^{2} \times t$

$\frac{22}{7} \times 7 \times 7 \times t$

t=154

$= \frac{22}{7} \times 7 \times 7 \times 154$

$23716 \: cm {}^{3}$
