Answer:
34 and 30
Step-by-step explanation:
8 times 3 = 34
and 34-4=30
divide 8 by 2 and you'll get 4
so, 34-4=30
B cause you take y times it by the circumference
Answer:
V ≈ 3367.6 cm³
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V =
πr³ ( r is the radius )
Here D = 18.6 , then r = 18.6 ÷ 2 = 9.3 , so
V =
× 3.14 × 9.3³
=
× 3.14 × 804.357
= 
≈ 3367.6 cm³ ( to the nearest tenth )
Answer:
see explanation
Step-by-step explanation:
Using the Pythagorean identity
sin²θ + cos²θ = 1 ( divide terms by sin²θ )
+
=
, that is
1 + cot²θ = cosec²θ ← as required
Answer:
14.4 km = 1440000
Step-by-step explanation:
1 km = 1000m
14.4 km = 1000 ×14.4
=14400 m
1 m =100 cm
14400 m = 100 × 14400
= 1440000 cm
