A circular cover to a swimming pool has a diameter that is 1.8 times the diameter of the cover to a hot tub. If the area of the swimming pool cover is about 254 square feet, what is the area of the hot tub cover in square feet? Round to the nearest foot.

141 square feet

Step-by-step explanation:

254 / 3.14 = 80.89

80.89 / 1.8 = 44.93

44.93 x 3.14 = 141.08

Being rounded to the nearest foot would mean that the hot tub cover is about 141 square feet.

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
