What is the diameter of circle with a circumference 240cm?
To find the diameter of a circle when given the circumference, you can use the formula: circumference = π * diameter. In this case, the circumference is 240cm. So, 240 = π * diameter. To solve for the diameter, you divide both sides by π, giving you diameter = 240 / π ≈ 76.39 cm. Therefore, the diameter of the circle is approximately 76.39 cm.
Explain how to use the distributive property to find 20x12?
The distributive property is not used for simplified multiplication. See http://www.algebrahelp.com/lessons/simplifying/distribution for information about how to use the distributive property to simplify other equations. 20 x 12 is already simplified, so the proper way to solve it is 12 x20 ----- 240 You could potentially factor and use the commutative property to find a simpler equation, ex. 20x12 -- break 20 into 10 and 2 10x2x12 -- multiply 2 by 12 10x24 -- multiply by 10 240
