D = π(bore / 2)² · stroke · n
can be rewritten as
D = π(1/2 * bore)² · stroke · n
If bore = k /2, and stroke = h, and # of cylinders = n = 8, then
D = π(1/2 * k/2)² · h · 8
= 8π*h(k/4)²
= 8π*h(k²/16) since (k/4)² = k²/4² = k²/16
= π*h*k²/2
Answer for the first part: D = π*h*k²/2
For second part, if bore = 4 inches, stroke is 3.4 inches, and # cylinders = n = 4, then
D = π(1/2 * bore)² · stroke · n
D = π(1/2 * 4)² · 3.4 · 4
D = 170.9 cubic inches
Answer
Rational B,D,J,k
Integers G
Whole E,G
IRRATIONAL A,C,F,h,I,L
Step-by-step explaining
Whole number is just numbers but with a zero for example 0,1,2,3,4,5,6,……….
Natural number is just like the whole number but without the zero . For example 1,2,3,4,5,6,…..
Integers, The set of integer is all the whole numbers and their opposite for example -3 -2 -1,0,1,2,
Irrational : non- terminating , non-repeating decimal
Can’t be written as a ratio
For example pie , 3.7685922331
Rational can be written as a ratio like fraction
Including fractions and only terminating and repeating decimals for example 1/5 , 0.33333333333……,1.4
