Sudut dan Radian

Penjelasan dengan langkah-langkah:

360⁰ = 2π rad

1. 210⁰ = x rad

x = 210⁰/360⁰ x 2π

= 7 / 12 x 2π

= 7 / 6 x π

= 7/6 π rad

2. 0,4 π rad =

x = 0,4π/2π x 360⁰

= 4π/20π x 360⁰

= 1π/5π x 360⁰

= 1/5 x 360⁰

= 72⁰

3. 3/4π rad =

x = 0,75π / 2π x 360⁰

= 75π/200π x 360⁰

= 3π/8π x 360⁰

= 3/8 x 360⁰

= 135⁰

4. 225⁰ = ... rad

x = 225⁰/360⁰ x 2π rad

= 5/8 x 2π

= 5/4 x π

= 5/4 π rad

5. 2 3/5 π rad = ...

x = 13/5π/(2π) x 360⁰

= 13/5πx1/2π x 360⁰

= 13/10 x 360⁰

= 1,3 x 360⁰

= 468⁰
