Roco draws two shapes. One of his shapes is 4 times longer and 4 times wider than the other. He found that the perimeter of the larger shape is 6 times larger than the perimeter of the smaller shapes and that the area is 16 times larger. Is he correct? What did he calculate correctly: area, perimeter or both?

The answer of the above is

The answer to your question is b’(16,14)

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 )
