Gap-fill

Ask the student a question, and give any hints about how they should answer this part.


	radius = $\var{a}$ cm

Give your answers to 2 decimal places. Use either the $\pi$ button on your calculator or the value $\pi = 3.142$ .

The area of this circle is Gap 0. $cm^2$ .

The circumference of this circle is Gap 1. $cm$

Advice

Recall that for a circle with radius $r$ , the area, $A$ , and circumference, $C$ , are given by the formulae

$A = \pi r^2$ , $C= 2 \pi r$

For a comprehensive list of the formulas for the perimeters, areas and volumes of 2-d and 3-d shapes see http://www.sciencehq.com/math-formulas/mensuration-formulas.html

Give a worked solution to the whole question.
