A spherical globe has a diameter of 10 inches. What is the approximate volume of the globe?

adelina 88 [10]

Answer:

523.33 in^3

Step-by-step explanation:

A sphere is a 3-dimensional version of a circle. An example of a sphere is a ball

Volume of a sphere = $\frac{4}{3}$ π $r^{3}$

Where

π = 3.14

r = radius

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

diameter = 2r

Radius = 10 in / 2 = 5 inches

$\frac{4}{3}$ × 3.14 × $5^{3}$ = 523.33 $in^{3}$

A certain species of tree grows an average of 0.5 cm per week. Write an equation for the sequence that represents the weekly hei

Anestetic [448]

For this we will use equation:

H = starting height + rate_of_growth*periods
We can mark H with index w to represent how many weeks have passed.
Because all of this we can write:

Hw = 200 + 0.5*w

To calculate height after some number of weeks all you need to do is to exchange w with number of weeks.

What is the area of a flour tortilla that has a 14-centimeter radius?

kykrilka [37]

The formula for the area of a circle is
$\pi {r}^{2}$
so you simply plug your value for radius into the equation!
$\pi {(14)}^{2}$
Square 14
$196\pi$
And Multiply by pi!
615.75 cm^2 approximately!
I hope this helps!
