Answer:
Step-by-step explanation:
Mp=$1200
Let sp be x
SP=MP-discount% of MP
x=1200-15/100 * 1200
x=120000-18000/100
x=102000/100
x=1020
the amount of money person saves=MP-SP
=$1200-$1020
=$180
therefore he saves $180
If circumference = (2 * PI * radius) then we solve for radius
radius = circumference / (2 * PI)radius = 25.142758 / 22/7 * 2radius = <span><span>4.00

circle area = PI * radius^2circle area = 22/7 * 4^2circle area = 22/7 *16
