The clock has a diameter of 18 inches. At 8 o'clock, what is the area of the sector formed by the two hands of the clock? Round
Drupady [299]

Answer:

The area of the sector is 84.8 in.² to the nearest tenth

Step-by-step explanation:

∵ the clock is a circle

∴ The measure of angles between each two hours = 360° ÷ 12 = 30°

∵ At 8 o'clock the hour hand pointed on 8 and the minute hand pointed on 12

∴ There are 4 angles between the two hands

∴ The central angle subtended by the arc = 4 × 30° = 120°

∵ The Area of the sector = \frac{x}{360} \pi r^{2} where x is the central angle subtended by this arc

∴ Area sector = \frac{120}{360} × π × (18/2)²

∴ Area sector = \frac{1}{3} × π ×81 = 27π = 84.8 in² to the nearest tenth

kobusy [5.1K]

Answer:

  19.193 million

Step-by-step explanation:

Put the given value in the formula and do the arithmetic.

  P(220) = 19.71/(1 +61.22e^(-0.03513·220))

  P(220) = 19.71/(1 +61.22e^-7.7286) = 19.71/(1 +0.02694046)

  P(220) ≈ 19.193 . . . million
