What is the area of a circle if the diameter is 16 millimetres

201.1 mm²

Step-by-step explanation:

given that the diameter is 16mm,

radius = diameter ÷ 2 = 16÷2 = 8 mm

area of a circle is given by

A = πr², where

π=3.142

r = radius = 8 mm

Substituting these into the equation,

A = πr²

= 3.142 (8)²

= 201.088 mm²

= 201.1 mm² (rounded to nearest tenth)

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.
