We know that Area of a circumference=π*r² for diameter=21.2 cm---------> r=10.6 cm A=π*10.6²--------> A=π*112.36 -------> A=352.81 cm²
if 2π radians (full circumference) has an area of -----> 352.81 cm² 3π/5 radians-------------------------------------> X X=[(3π/5)*(352.81)]/2π---------> X=105.84 cm²
Hello! So for this question, all you have to do is add the numbers up to get the total cost. Groceries were $102.34 and the new shoes were $53.36. 102.34 + 53.36 = 155.7. Lorena spent $155.70 total.
