What is the volume of this sphere? use 3.14 for pi and round to the nearest hundredth when necessary.

Mathematics

Harrizon [31]3 years ago
4 0

The volume of the sphere is 900 cm³

Step-by-step explanation:

  • Step 1: Given the diameter of the ball = 12 cm. Find radius.

Radius = diameter/2 = 12/2 = 6cm

  • Use the formula for volume of a sphere to find the volume.

Volume of the ball = 4/3 πr³

                              = 4/3 × 3.14 × (6)³

                              = 904.32 cm³ ≈ 900 cm³ (nearest hundredth)

Jenna feeds her cat twice a day. She gives her cat 3/4 can of cat food each time. Jenna is having a friend take care of her cat
Anarel [89]

Given:

Number of times Jenna feeds her cat = 2

Cat food each time =\dfrac{3}{4}\text{ can}

Number of days = 5

Number of cans she bought = 8

To find:

Did Jenna buy enough cat food.

Solution:

Required food for each time  =\dfrac{3}{4}\text{ can}

Jenna feeds her cat twice a day.

Required food for a day =2\times \dfrac{3}{4}\text{ can}

                          =\dfrac{3}{2}\text{ can}

Required food for 5 days =5\times \dfrac{3}{2}\text{ can}

                           =\dfrac{15}{2}\text{ can}

                           =7.5\text{ can}

Since, 7.5 cans < 8 cans, therefore, Jenna buy enough cat food for her cat.

Give the slope-intercept form of the equation of the line that is perpendicular to –7x – 8y = 12 and contains P(–3, 1)
snow_lady [41]

Answer:

(-7/8)

Step-by-step explanation:

the line is  -7x -8y =12

its slope = -(-7/-8)= -7/8

it passes through P(-3, 1)

(y-1)=(-7/8)(x+3)

y-1 = (-7/8)x - 21/8

y = (-7/8)x -13/8

If me.Arenth wants to put new carpeting in the room shown, how many square feet should he order
Liula [17]

By definition, the area is given by:


A = w * l  


Where,


w: width


l: length


We have two expressions for the length:


L = 14\\L = 5 + 3c


Since the length is the same, we equate both expressions:


5 + 3c = 14  


From here, we clear the value of c:


3c = 14 - 5\\3c = 9  


c = \frac{9}{3}\\c = 3  


Then, we have that the width is given by:


W = 6c-8  


Substituting the value of c we have:


W = 6 (3) -8\\W = 18-8\\W = 10  


Finally, the area is given by:


A = w * l\\A = 10 * 14\\A = 140 ft ^ 2  


Answer:


he should order 140 square feet
