18. If the following actions are taken:1. Circle object is chosen and selected a center/first point2. Click “diameter” in the command bar3. Input 300What will happen with the circle?a. The circle radius will be 300 unitsb. The circle diameter will be 150 unitsc. The circle radius will be 150 unitsd. The circle diameter will be 300 units

If a user enters a diameter value in the variable diameter, how would we use this to draw the correct sized circle?var circle = new Circle(diameter);circle.setPosition(100,100);add(circle);var circle = new Circle(diameter*2);circle.setPosition(100,100);add(circle);var circle = new Circle(diameter/2);circle.setPosition(100,100);add(circle);var circle = new Circle(diameter%2);circle.setPosition(100,100);add(circle);

37. Choose the next step if the following actions are taken if a circle needs to be replicated 20times with the same dimensions, with distance of 300 units from the base circle’s centerand increment of 10°.1. Type circle command and enter specific dimension.2. Select copy command and select the center of the circle.3. _____________________________.a. Set the polar tracking to 10° increment and as you copy type in 300 units, click tabthen enter the angle.b. Set the orthomode to 10° increment and as you copy type in 300 units, click enterthen enter the angle.c. Set the polar tracking to 30° increment and as you copy type in 300 units, click tabthen enter the <10.d. Set the orthomode to 10° increment and as you copy type in 300 units, click tab thenenter <10.

The radius of circle is given as 2.8 cm to 2 significant figures(a) If C is the circumference of the circle, determine the limits between which C/πlies(b) By taking ∏ to be 3.142, find, to 4 significant figures the line between which thecircumference lies.3. The length and breath of a rectangular floor were measured and found to be 4.1m and 2.2 m respectively. If possible error of 0.01 m was made in each of themeasurements, find the:(a) Maximum and minimum possible area of the floor(b) Maximum possible wastage in carpet ordered to cover the whole floor(c)4. In this question Mathematical Tables should not be usedThe base and perpendicular height of a triangle measured to the nearestcentimeter are 6 cm and 4 cm respectively.Find(a) The absolute error in calculating the area of the triangle(b) The percentage error in the area, giving the answer to 1 decimal place
