Luas lingkaran yang berjari-jari 70 cm adalah ?

UceLLs

$\small\boxed{\tt{= \pi \times {r}^{2}}}$

$\tt = \frac{22}{7} \times {70}^{2}$

$\tt = (22 × 70 × 70) ÷ 7$

$\tt = 107.800 ÷ 7$

$\tt = 15.400 cm³$

15.400 cm²

Penjelasan dengan langkah-langkah:

Dik.

- Jari - Jari = 70 cm

Dit.

- Luas = .....?

penyelesaian

- Luas :

L = π × r × r

L = $\frac{22}{7}$ × 70 cm × 70 cm

L = 22 × 10 cm × 70 cm

L = 220 cm × 70 cm

L = 15.400 cm²

=======================================

semoga bermanfaat

selamat belajar dan semangattt
