Answer:
y ≤ 5
Step-by-step explanation:
2.45cm=1 in
times both sides by 63
160.02cm=63 in
about 160cm
Answer:
38 mm³
Step-by-step explanation:
Calculate the volume of the cylinder and of the cone separately.
1. Volume of cylinder
The formula for the volume V of a cylinder is
V = πr²h
Data:
D = 4 mm
h = 2 mm
Calculations:
a. Calculate the radius
D = 2r
r = D/2 = 4/2 = 2 mm
b. Calculate the volume
V = 3.14 × 2² × 2 = 25.12 mm³
2. Volume of cone
The volume for the volume (V) of a cone is
V = ⅓πr²h
V = ⅓ × 3.14 × 2² × 3
V = 18.85 mm³
3. Calculate the total volume
V = 25.12 mm³ + 12.57 mm³ = 38 mm³
No the length of a triangle 2 smaller sides has to be greater than the sum of the other longer side
Below are the solutions:
A)
Ohio: 8.23 * 10^5
US: 3.19 * 10^8
B)
(3.19 * 10^8)/(8.23 * 10^5) = 3.19/8.23 * 10^8/10^5
= 3.19/8.23 * 10^3 = 0.387606318 * 10^3
= 387.606318
The population of US is 387 times larger than that of Ohio's
