A hemisphere has a diameter of 26 centimeters. What is the volume of a sphere with the same radius?
salantis [7]
r= \frac{d}{2}= \frac{26}{2} \;\Rightarrow r=13\,cm  \\  \\ 
V= \frac{4}{3} \pi r^3 \\  \\ 
V= \frac{4}{3} \pi \,(13)^3 \\  \\ 
V= \dfrac{4\cdot 2197}{3} \pi \\  \\ 
V= \frac{8788}{3} \pi\approx 9202,77\,cm^3

Answer:

x² - 16

Step-by-step explanation:

Given

(x - 4)(x + 4)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x + 4) - 4(x + 4) ← distribute both parenthesis

= x² + 4x - 4x - 16 ← collect like terms

= x² - 16

I need someone to solve this
LUCKY_DIMON [66]

Answer:

?? = 900

Step-by-step explanation:

Solve algebraically

let x be ball and y be cube

x + y = 100

x - y = 80

xy = ??

We can solve by elimination. Eliminate one of the variables by adding OR subtracting the entire equations. I will add.

.     x + y = 100

<u>+    x - y = 80</u>       y + - y = y - y = 0; The variable is eliminated

.        2x = 180      Divide both sides by 2 to isolate x

.          x = 90

Substitute x = 90 into one of the equations.

x + y = 100

90 + y = 100  Isolate y by subtracting 90 from both sides

y = 100 - 90

y = 10

Find xy = ?? by substituting y for 10 and x for 90.

xy = (90)(10) = 900

Therefore the value of ?? is 900.
