Answer:

A = 81π cm²

Step-by-step explanation:

The area (A) of the cross section is calculated as

A = πr² ( r is the radius )

Find r by using the given circumference.

Given the circumference is 18π and circumference (C) is

C = 2πr = 18π ( divide both sides by 2π )

r = 9, thus

A = π × 9² = 81π cm²

Write an equation in point-slope form of the line that passes through the given point and has the given slope. (3, 2); m = 2/3
77julia77 [94]

Answer:

y - 2 = \frac{2}{3}(x-3)

Step-by-step explanation:

Point-slope form: y - y1 = m(x - x1)

Slope: \frac{2}{3}

Point: (3, 2) = (x1, y1)

To write the equation in point-slope form, we need to know the values of the slope and one point. Since we've already been given those values, all we have to do is input them into the equation:

y - y1 = m(x - x1)

y - 2 = \frac{2}{3}(x-3)

The equation in point-slope form is: y - 2 = \frac{2}{3}(x-3)

In converting 30 pounds to ounces, what unit (omit the number) would you
gladu [14]

Step-by-step explanation:

to convert pounds into ounces you'd

actually multiply 16 by 30:

30 * 16

you're doing this because if one pound equals 16 ounces, if you have 30 pounds then you must've had more ounces. therefore you'd multiply.

which is 480 pounds

Enjoy!
