Answer:
see explanation
Step-by-step explanation:
The circumference (C) of a circle is calculated as
C = πd ( d is the diameter )
(4)
Here d = 18, thus
C = 18π in
(5)
Here C = 50π, thus
πd = 50π ( divide both sides by π )
d = 50 in
The radius r is one half of the diameter , thus
r = 50 ÷ 2 = 25 in
Answer:
47.7 square units
Step-by-step explanation:
The area of triangle ABC with two given sides and an inclusive angle =
1/2absinC
Where : a = 8, b = 12, C = 84
Area of Triangle ABC = 1/2 × 8 × 12 × sin 84
Area of Triangle ABC = 47.737050978 square units
Approximately to the nearest tenth = 47.7 square units.
A = 1/2(8)(10) + 1/2(6)(8)
A = 40 + 24
A = 64
answer
64 in^2
Answer:
hard to go without a graph see explanation
Step-by-step explanation:
from each point, count har far away it is from the dotted mirror line and then count that many in the opposite direction.
for example, the spikey point at the bottom is 3 units below the mirror line so count 3 units above the mirror line and that is where other point will be
