Answer:

2.4 m

Step-by-step explanation:

A fórmula para o comprimento do arco é dada como:

Comprimento do arco = 2πr (θ / 360)

Onde r = raio = 3cm

θ = Ângulo em graus = 45 °

Comprimento do arco = 2 × π × 3 (45/360)

Comprimento do arco = 2.356194m

Aproximadamente = 2.4 m

Round 0.971 to the nearest tenth​
Flura [38]

Answer:

1.0

Step-by-step explanation:

You are rounding to the nearest tenth, so you should have only 2 places remaining (0.0). So, you look to the 7 to change the 9. 7 is bigger than 5, so you round 9 up. Since 9 plus 1 equals 10, the final answer is 1.0.

Hope this helps! :)
