Find the surface area of a cylinder to the nearest tenth of a square unit use 3.14 for pi radius is 4.9ft h is 7.8ft

38.2
65.4
286.2
390.8

Solution:

The surface area of cylinder is given as:

Where, r is the radius and h is the height

From given,

r = 4.9 feet

h = 7.8 feet

Substituting the values we get,

Thus the surface area of a cylinder to the nearest tenth is 390.8 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.

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
