Answer:
18.84
Step-by-step explanation:
Circumference = 2πd
where d = diameter
the shape given has a diameter of 6
to find the circumference we simply plug in the value of the diameter as well as π into the formula
formula : C = πd
π = 3.14 and d = 6
C = 3.14(6) = 18.84cm
Answer:
Given coordinetes of triangle A(−2,3),B(8,3) and C(6,7)
AB=
[8−(−2)]

=
100
AC=
[6−(−2)]
2
+(7−3)

=
4+16
=
20
If ABC is a right angled triangle, then square of one side must be equal to sum of suare of other two sides.
AB

=100
and AC

)
2
+(
20
)

=100
∴AB

=AC
2
+BC

thus triangle satisfies the Pythagoras theorem
Hence, the triangle is right angled triangle.

Answer:
The boats are far apart by 4506.1 feet
Step-by-step explanation:
from the graph attached
i) BC = 1353
= 2761.82 feet
ii) BD = 1353
= 1744.28 feet
iii) the boats are far apart by = CD = CB + BD = 2761.82 + 1744.28 = 4506.1 feet
