I don't know if your school lets you simplify pi so I'll put two options; here's simplified pi. Step 1; Write Out Your Problem A = [tex] \pi [/tex] x 8^2 Step 2; Simplify 3.14 for [tex] \pi [/tex] A = 3.14 x 8^2 Step 3; PEMDAS/Solve for 8^2 A = 3.14 x 64 Step 4; PEMDAS/Multiply 3.14 by 64 A = 200.96 Step 5; Simplify In this case you don't need to simplify.
And here's the un-simplified pi; Step 1; Write Out Your Problem A = [tex] \pi [/tex] x 8^2 Step 2; PEMDAS/Solve for 8^2 A = [tex] \pi [/tex] x 64 Step 3; PEMDAS/Multiply pi by 64 A = 201.06192983 Step 4; Simplify A = 201.06
