Formula for a circle: A=Pi*r^2 Diameter:2ft Radius:1ft A=3.14*1^2 A=3.14 Multiply by 4 4 squares=12.56ft squared Formula for a square: A=s^2 A=4^2 A= 16ft squared To find leftover you need to subtract 12.56 ft from 16 ft to get 3.44 ft squared(A).
If each shirt needs eight buttons you find out what times (×) Eight equals (=) 80 8×10=80 So Eight buttons per shirt So together they made 10 shirts but they ask how many Timor made so you do 10 ÷ 2= 5
The formula is A=p (1+r/k)^kt A fund needed 30000 p Amount invested? R interest rate 0.1 K compounded semiannual 2 T time 1 year Solve the formula for p to get P=A÷(1+r/k)^kt P=30,000÷(1+0.1÷2)^(2×1) P=27,210.88
