Astandard letter-sized piece of paper has a length and width of 8.5 inches by 11 inches. a. find the area of one piece of paper.

To do area of this piece of paper, we take 8.5, and multiply by it 11. So, the answer would be 93.5

Area=legnth times width
width=8.5
legnth=11
area=11 times 8.5=93.5 in^2

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
