Kenji packed an exercise ball into a cylindrical package. The cylindrical package is made out of plastic. How much plastic was used to make the package? Express your answer in terms of π. Enter your answer in the box.

Answers

Answer:

45[tex]\pi[/tex]

Step-by-step explanation

The space that the package occupies is the volume of the cylinder. The volume of an object is the 3 dimensional capacity of the object.

Volume of a cylinder = h

Lets say r is the radius and h is the height of the cylinder.

Given that; h = 5 feet and r = 3 feet.

The required volume = [tex]\pi[/tex] ×  × 5

                                  = [tex]\pi[/tex]  × 9 × 5

                                 = 45[tex]\pi[/tex] cubic feet

Answers

Answer:

65/139 fraction form

0.47 decimal form

Answer:

Step-by-step explanation:

Total sample space , n (s) = 139

no of green candies , n (g) = 45

no. of yellow candies , n (y) = 20

Probability that is green or yellow is

P( g or y) = P(g) + P(y)

               = n(g) / n(s) + n (y) / n(s)

               = 45 / 139 + 20 / 139

               = 65 / 139

Answers

Answer: angle 1= 65 degrees, angle 2=115 degrees

Step-by-step explanation:

Both angles are complementary angles, or they together equal 180°, so you will add both expressions and set equal to 180. This will get you (3x+2)+(5x+10)= 180. We then solve for x.
8x +12 = 180. We subtract 12 on both sides.
8x = 168. We divide by 8 on both sides.
x=21
We can then plug x into each expression to get the angle for each.
Angle 1: 3(21)+2=65°
Angle 2: 5(21)+10=115°

The radius of a circle is 4 centimeters. What is the angle measure of an arc bounding a sector with area 2​ square centimeters?

Answers

Answer:

Measure of the arc = 14.32°

Step-by-step explanation:

Radius of a circle = 4 cm²

Area of the circle = πr²

Here, r = radius of the circle

Area of the circle = π(4)²

                             = 16π cm²

                             = 50.265 cm²

Since, area of a sector = [tex]\frac{\theta}{360}(\text{Area of the circle})[/tex]

Here, θ = Central angle subtended by the arc Or measure of arc

Area of the sector given as 2 cm²

2 = [tex]\frac{\theta}{360}(50.265)[/tex]

θ = 14.32°

Therefore, measure of the arc = 14.32°.
