Area = 64π

Circumference = 2πr or πd

diameter = 16 (Diameter times π = 16π so this is obvious)

radius = diameter divided by 2 = 8

Area = πr², so π times 8² = π times 64 = 64π

The perimeter of a scalene triangle is 14.5 cm. The longest side is twice that of the shortest side. Which equation can be used
wel

Answer:

9.3 + b = 14.5

Step-by-step explanation:

Longest side of ∆ = 2a = 6.2 cm

If the shortest side is, a, and we are told that the longest side is twice the shortest side, therefore, length of shortest side is

The sum of the 3 sides = perimeter = 14.5 cm

Thus,

a + 2a + b = 14.5 cm

Plug in the values of a and b

3.1 + 6.2 + b = 14.5

The equation that can be used to find the side lengths is 9.3 + b = 14.5

Carter randomly selected some red and yellow clothing items at a store and recorded their prices. The tables below show the data
sukhopar [10]

Answer:

You have to compare if true some of the statements.

Most of these type questions would be compare the first three data

1. Prices of red to yellow mean we need to add them all up to begin with. 10 x £29.95 + 5 x 35.99 etc. = 15 items or add one zero (x10) to 29.95 and for 35.99 we add zero (x10) then divide by  2  ie) 359.9/2 = 360/2-0.2 = 180 - 0.2 = $179.98

2. Higher and lower comparisments we just take away from total.

3. The difference or how much more something is we subtract from the full total.

This would be a 4 way thought process below;

1. Prices in $ could mean groups, mean high or low we need to count how many items and add up all the prices to find the mean by adding them together.

2. Colour's could mean more red than yellow over a certain price or under a certain price.

3. Colour could also mean how many as a combined data were higher or lower than a certain price. ie) Higher than $29.99 would mean all the data set at $30.00  more. LEss would mean lower than $29.98

4. Mean and fx would be all the prices added together + all the items togather for the fx we multiply the individual groups and create a new box. We then multiple it to the other totals. This can also help establish or be compared to the percentage for advanced data tables.
