What is the answer

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 )

♡   the answer will be d. 0.7! i just had the last last week : p ♡

First step simplify de parentheses=14(-23)2+13second step multiply 14,-23 and 2=-616+13third step do the addition and remember that when de numbers have a different sign they substract so i this ocasión we substract because one number is positive the other is negative=-603and that is you’re answer

160*320*480*640*.5=7,864,320,000 cubic units.. hope this is correct but yet no promises..    : )
