The correct answer is 0.99kg/L

Explanation:

To find the density, the first step is to convert the weight (mass) and the volume into the appropriate units.

The volume is 8.5 gallons and this needs to be converted to litters. In this case, multiply the volume in gallons by 3.785 because each gallon contains 3.785 liters.

8.5 x 3.785 = 32.1725 liters

The mass is 70 pounds and this needs to be converted to kilos. In this case, divide the pounds by 2.204 considering each kilo contains 2.204 pounds.

70 ÷ 2.2046 = 31.751 kilos

Now, find the density by dividing the mass into the volume.

Density= 31.751 kg ÷ 32.1725 L

Density = 0.98 kg/L

This means the density is 0.9.868 kg/L and this can be rounded as 0.99 kg/L

What is the approximate surface area of the sphere if circumference is 37.68?
damaskus [11]

The surface area of a sphere is  A = 4 π R² .

Sadly, the question doesn't give you 'R', so you have to
back it out of the circumference.

                           Circumference = π (diameter)

Divide each side by π :  Diameter = circumference / π

Radius = 1/2 diameter:  Radius = circumference / (2 π)

                                       Area = 4 π R²  =

                                                 4 π (circumference/2π)² =

                                                 4 π (circumference)² / 4 π²

Divide top and bottom by  4π :  Area = (Circumference)² / π

         Circumference = 37.68 units

         Area =  (37.68)² square units /π =

Find the area of the shaded region to the nearest tenth. See picture for full problem. Please and thank you so very much!
Romashka [77]

Answer:

66.3 sq ft

Step-by-step explanation:

Here's the plan: we'll find the area of the circle then subtract the area of the triangle.

Area of circle:

A = pi•r^2

= pi•6^2

= 3.14•36

~= 113.04

Area of triangle:

A = 1/2bh

= 1/2(10.39)(9)

The height is the 6+3 in the image.

~= 46.755

Subtract to find

Area of Shaded:

113.04 - 46.755

= 66.285

Round to nearest tenth.

~= 66.3 sq ft
