The diameter of a ceiling fan, blade tip to blade tip, is 120 centimeters. a) About how many whole revolutions does it take for the fan to move 1000 meters?


b) If the fan rotates at 40 revolutions per minute, about how long does it take to move 1000 meters? Round to the nearest minute.

it is x equals 3   plese mark me really need it

step-by-step explanation:

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
