Answer:
(b) 80/3π in³
Step-by-step explanation:
The volume of a circular cone is given by ...
V = 1/3πr²h . . where r is the radius (half the diameter) and h is the height
Your cone has r = 4 inches and h = 5 inches, so its volume is ...
V = (1/3)π(4 in)²(5 in) = 80/3π in³
The volume of the cone is exactly (80/3)π cubic inches.
Answer:
10m
Step-by-step explanation:
Radius is half the diameter.
So, 5x2 = 10
Answer: 10m

Answer:
21.9°
Step-by-step explanation:
In ΔHIJ, the measure of ∠J=90°, HI = 8 feet, and JH = 1.9 feet. Find the measure of ∠H to the nearest tenth of a degree.
We solve this above question using the Sine rule
a/sin A = b/sin B
In ΔHIJ, the measure of ∠J=90°, HI = 8 feet, and JH = 1.9 feet.
Hence:
HI/∠J = JH/∠H
= 8/sin 90° = 1.9/sin ∠H
Cross Multiply
∠H = arc sin(sin 1.9 × 90/8)
∠H = 21.9°
Answer:
Flying squirrel have to glide is for 9.8 meters approximately.
Step-by-step explanation:
Here we can use Pythagoras theorem.
Height is 9 , base is 4.
We need to find the hypotenuse measure.
So, let's use Pythagoras theorem 
Plug in a as 9 and b 4.
Simplify the left side of the equation
Take square root on both sides.
c=9.8 meters.
