A small sphere shaped jar has a 8 cm radius.what is the volume of the bowl

1 answer:

3 0

To find the volume of a sphere you have to use the equation
V = 4/3 π r³ Substitute in the r value (8)
V = 4/3 π 8³ Simplify the exponent
V = 4/3 π 512 Multiply 4/3 and 8 (In other words ; (4 x 512) / 3)
V = 682.67 π Multiply
V = 2143.5838 cm³

crimeas [40]

Answer:

Faisal receives $241

Ahmed receives $482

Walid receives $723

Step-by-step explanation:

I am going to build a system of equations to solve this question.

We have that:

x is the amount that Faysal received.

y is the amount that Ahmed received.

z is the amount that Walid received.

Ahmed, Walid and Faisal made $1446 profit from selling used books.

This means that

$x + y + z = 1446$

Ahmed to receive double amount of Faisal

This means that $y = 2x$

Walid to receive triple amount of Faisal.

This means that $z = 3x$

$x + 2x + 3x = 1446$

$6x = 1446$

$x = \frac{1446}{6}$

$x = 241$

$y = 2x = 2*241 = 482$

$z = 3x = 3*241 = 723$

Faisal receives $241

Ahmed receives $482

Walid receives $723

The length of the base of a triangle is twice its height. if the area of the triangle is 225 square kilometers, find the height

Anon25 [30]

Let
x----------> length of the base
y----------> height

we know that
[the area of triangle]=[length of the base]*[height]/2
x=2y
A=225 km²
225=x*y/2---------> 225=(2y)*y/2-----> y²=225--------> y=15 km
x=2y--------> x=2*15------> x=30 km

the answer is
the height is 15 km

Which statement is true regarding the functions of the graph?

gregori [183]

Answer:

f(- 3) = g(- 3)

Step-by-step explanation:

f(x) and g(x) are equal at the point of intersection.

When x = - 3 , f(- 3) = - 4 and g(- 3) = - 4

Thus

f(- 3) = g(- 3)
