Answer:
4) 33.51 cu.in
5) 84.82 cu.m
7) 2.09 cu.ft
8) 1047.197 cu.cm (CC)
11) 163.62 cu.in
Step-by-step explanation:
Volume is h/3x πr^3
4) 4/3 x π x 2^3 = 33.51
5) 3/3 x π x 3^3 = 84.82
7) 2/3 x π x 1^3 = 2.09
8) 8/3 x π x 5^3 = 1047.197
11) 10/3 x π x 2.5^3 = 163.62
Answer:
95π
Step-by-step explanation:
area of a circle=πr²
radius of the big circle = 24/2=12
area of big circle = π(12)² = 144π
are of small circle = π(7)² = 49π
shaded area = area of big circle - area of small circle
= 144π-49π
= 95π
Answer:
66
Step-by-step explanation:
The correct answer is D. No because the permutations rule would be used to determine the total number of combinations.
Explanation:
The difference between a combination and a permutation is that in permutations the order is considered. This applies to the numbers in a lock because these need to be in order. Therefore, to analyze the permutations in a lock, the rule for permutations should be used. This includes the general formula P (n,r) =
; in this, n is the number of objects and r refers to the objects used in a permutation. Thus, the term "combination" is inappropriate because this is a permutation, and the permutation rule should be used.
