Step-by-step explanation:
1)radius = 10 in (given), diameter = 2*radius = 2(10 in) = 20 in
formula for circumference => 2πr => 2π(10)
circumference = 20π in
2)diameter = 12 ft (given), radius = 1/2*diameter = 1/2(12 ft) = 6 ft
formula for circumference => 2πr => 2π(6)
circumference = 12π ft
3)radius = 3 m (given), diameter = 2*radius = 2(3 m) = 6 m
formula for circumference => 2πr => 2π(3)
circumference = 6π m
4)diameter = 18 cm (given), radius = 1/2*diameter = 1/2(18 cm) = 9 cm
formula for circumference => 2πr => 2π(9)
circumference = 18π cm

the determinant for your matrix is
Answer: There are 120 boats in the marina.
Step-by-step explanation:
Let's suppose that there are N boats
We know that 5/6 of them are white, then we have: (5/6)*N white boats.
The remaining is: N - (5/6)*N = (1/6)*N
We know that 2/5 of the remaining are blue, then we have:
(2/5)*(1/6)*N blue boats
And the rest are red, the rest is:
(1/6)*N - (2/5)*(1/6)*N = (3/5)*(1/6)*N
Then we have (3/5)*(1/6)*N red boats.
And we know that there are 12 red boats, then:
(3/5)*(1/6)*N = 12
Now we can solve this for N, which is the total number of boats in the marina.
N = 12*(6)*(5/3) = 120
There are 120 boats in the marina.
