+23246 In each case, find the area of the outer figure and subtract the areas of the inner figures.
1) Area of the outer figure: A = 12 cm x 12 cm = -------
Area of an inner circle: A = pi·32 = --------
Area of the other circle: A = pi·32 = --------
Final answer: answer #1 - answer #2 - answer #3 = -------
2) The radius of the outer circle is 8 cm + 4 cm = 12 cm.
Area of the outer circle: A = pi·122 = -------
Area of the top inner circle: A = pi·42 = -------
Area of the bottom inncer circle: A = pi·82 = --------
Final answer: answer #1 - answer #2 - answer #3 = -------
