Can some one help me with this question.

Area of the small circle = [tex] \pi [/tex]r[tex] x^{2} [/tex] = 3.14 x 7[tex] x^{2} [/tex]= 153.86
Area of the big circle = [tex] \pi [/tex]R[tex] x^{2} [/tex]=3.14 x 14[tex] x^{2} [/tex]= 615.44
The shaded area = area of the big circle - area of 2 small circle = 615.44-2x153.84≅308
The answer is 308
