Answer:

The area of the circle is 314mm²

Step-by-step explanation:

To solve this problem we have to use the formula for calculating the area of a circle

a = area

π = 3.14

r = radius

d = diameter

r = d/2

r = 20mm / 2

r = 10mm

a = π * r²

we replace the known values

a = 3.14 * (10mm)²

a = 3.14 * 100mm²

a = 314mm²

The area of the circle is 314mm²

Cindy has a chocolate box whose length is 12 cm, height of 8 cm, and width of 6 cm. Find the volume of the box?

Hello there I hope you are having a great day :) Cindy has a chocolate box whose length is 12 cm, height of 8 cm, and width of 6 cm. Find the volume of the box?

V = L x W x H

Volume = length x Width x Height.

12cm x 6cm x 8cm = V = 576cm^3

so the answer is 576cm^3

Hopefully that helps you :)

Answer:

Step-by-step explanation:

$x^2-6=16x+30\\\mathrm{Subtract\:}30\mathrm{\:from\:both\:sides}\\x^2-6-30=16x+30-30\\Simplify\\x^2-36=16x\\\mathrm{Subtract\:}16x\mathrm{\:from\:both\:sides}\\x^2-36-16x=16x-16x\\\Simplify\\x^2-16x-36=0$
