The Chess Club made brownies for the Winter Carnival. Eric said they should sell the
brownies by the ounce because they could
never cut the brownies all the same size. To
prove his point, he asked five of the
members of the club to cut a brownie
exactly to be two inches by two inches. Then
he weighed each brownie. The five brownies
weighed four ounces, 3.6 ounces, 3.9 ounces,
3.2 ounces, and two ounces. What was the
total weight of the five brownies?

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 )
