For an sphere what would be the formula

Answers

Answer 1

Answer: A sphere's volume formula is :

${ V }_( sphere )=\frac { 4 }{ 3 } \cdot \pi \cdot { r }^( 3 )$

and surface are formula is:

${ V }_( a )=4\cdot \pi \cdot { r }^( 2 )$

Where r is radius.

Answer 2

Answer:
For an sphere:

Diameter = (2) x (radius)

Radius = (1/2) x (diameter)

Surface area = (4) x (pi) x (radius)²

Volume = (4/3) x (pi) x (radius)³

67% of 8.7 = ___ estimate

Answers

The answer is 5.829 but with and estimate... 6

Final answer:

To calculate 67% of 8.7, we convert 67% to its decimal form, 0.67, and multiply it by 8.7, getting an estimated value of 5.83.

Explanation:

To calculate 67% of 8.7, we should multiply 8.7 by 0.67 (which is the decimal equivalent of 67%).

Let's do the calculation:

Convert 67% to decimal form: 67 / 100 = 0.67
Multiply 8.7 by 0.67: 8.7 × 0.67 = 5.829.

So, 67% of 8.7 is approximately 5.83. This is an estimate, since we rounded the final answer to the nearest hundredths place for simplicity. As always, check with your teacher or test instructions for how many decimal places they want you to round to.

#SPJ3

The difference between two whole numbers is 14. Their product is 1,800. What are the two numbers?

Answers

The numbers are "x" and "y", therefore, we suggest this system of equations:
x-y=14
xy=1800
We can solve by substitution method.
x=14+y

(14+y)y=1800
14y+y²=1800
y²+14y-1800=0

Now, we solve this square equation:
y=[-14⁺₋√(196+7200)] / 2=(-14⁺₋86)/2
We have two solutions:

y₁=(-14-86)/2=-50 ⇒x=14+y=14-50=-36
y₂=(-14+86)/2=36 ⇒x=14+y=14+36=50

Answer: we have two solutions:
Solution1: The first number is -36 and the other number is -50
Soltuion2: The first number is 50 and the other number is 36
