Basically, you just do what comes first since just only the operation of addition. NOTE: This is important to remember! You read equations left from right.

1. -20 + -10 = -30
2. -30 + 15 = -15.

Your answer is -15!

Diameter of wheel of car is 35 cm . how much distance will it cover in 1000 revolution.

kirill115 [55]

Answer: 35000π cm.

Step-by-step explanation:

First find circumference

Circumference = 2 × π × radius

Circumference = 2 × π × ( diameter / 2 )

Circumference = 2 × π × ( 35 / 2 )

Circumference = 35 × π cm

Now,

1 revolution = 1 circumference

1000 revolution = 1000 circumference

1000 revolution = 1000 × (35 × π)

1000 revolution = 35000π cm.
