Answer:

77 in ^2 is the best estimate

Step-by-step explanation:

We can get the total area from the sum of the triangle and the semi circle

semicircle

1/2 the area of the semicircle

A = 1/2  pi r^2

   1/2 (3.14) ( 4^2)

    25.12

Now find the area of the triangle

The base is 16 -r = 16-4 = 12

The height is 8

A = 1/2 bh

   = 1/2 (8) (12)

   = 48

The total area is 25.12+48 =73.12

A ball has a radius of 8 cm. What is the volume of the ball? Use 3.14 for pie Round your answer to the nearest tenth of a cubic
AveGali [126]

The volume of the ball is 33.5 cubic centimeter.

<u>Step-by-step explanation:</u>

It is given that, a ball has a radius of 8 cm.

We know that, the ball is in shape of the sphere.

The question is asked to find the volume of the ball.

To find the volume of the ball, you need to use the formula for volume of the sphere.

Volume of the sphere = (4/3)πr³

where,

  • π has the default value of 3.14
  • r is the radius of the ball.

Volume of the ball = (4/3)× 3.14× 8

⇒ 33.49

⇒ 33.5 (rounded to the nearest tenth)

⇒ 33.5 cubic centimeter.

∴ The volume of the ball is 33.5 cubic centimeter.

The water temperature required for a certain manufacturing process is 134°F. However, the process allows for a variation of 7°F
Y_Kistochka [10]

Answer:

The temperature that represents a smaller value would be the one with negative eighty (or -80) degrees Fahrenheit. Although it is negative, the value of 80 does not mean it has a smaller value as to 134 degrees. It is just that the difference between the absolute values of the two show that 134 degrees Fahrenheit has a bigger value.
