Hint:
Diameter(d)= 2 radius(r)
circumference= 2πr= πd
1. diameter= 19 × 2 = 38 inches
circumference= 3.18(38) = 119 inches (3 s.f.)
Note that I use 3.18 instead of π because the question states to use 3.14 for π.
Likewise, if you are given the diameter, divide it by 2 to find radius. Let's try a question which only gives you the diameter.
4. radius= 22 ÷ 2 = 11cm
circumference= 3.14(22) = 69.1cm (3 s.f.)
The answer is b .........
The function y = 5x has a rate of change that is in between the equation y = 4x and y = 6x.
In an equation, the rate of change is also called the slope. It is the amount that a number is increasing by. We put that value in front of the x in most equations.
In the equal that I gave, the 5 is in between the rates of 4 and 6.

Answer:
Mai is wrong since both travel the same distance in the same amount of seconds
Step-by-step explanation:
3 centimeters in 3 seconds is 1 centimeter a second for the slug
6 centimeters in 6 seconds is 1 centimeter a second for the snail
so both travel the same distance
