Step-by-step explanation:
easy peasy here we go..
so first circumference = 2π R
now it is given that circumference - 30 cm = Diameter;
Diameter = 2πR - 30 = 2 R { diameter = 2 times Radius}
now solving equations:
2πR -2R = 30
πR - R = 15
R ( π - 1 ) = 15
R ( 22/7 - 1) = 15
R ( 15/7 ) = 15
R = 15 x 7 / 15
R = 7 cm

Answer:
Step-by-step explanation:
To find the value of Coach Velez's total bill, first we must figure out how much the total of all of the ice cream sundaes were.
To do this, we must multiply the number of sundaes (8) by the cost of each sundae ($5.35).
8 * 5.35 = $42.80
However, Coach Velez also left a tip of 15%. To find out how much Coach Velez tipped, we have to multiply his regular bill ($42.80) times the amount he is tipping (15% or 0.15)
$42.80 * 0.15 = $6.42
Finally, we just have to add the bill ($42.80) and the tip ($6.42) together to find Coach Velez's total amount.
$42.80 + $6.42 = $49.22
Coach Velez spent $49.22 in all.
