Time = t = ?
Distance 1 = d1 = 224 miles
Distance 2 = d2 = 175 miles
speed1 = v1 = d1/t
speed2 = v2 = d2/t
Also, speed 1 = 14 + v2 (Given in the data)
OR speed 1 = 14 + d2/t
speed 1 = 14 + 175/t
224/t = 14 + 175/t
multiplying both sides (each term) by "t" we get
224 = 14t +175
OR 14t = 49
t = 3.5 hours
now, speed of 1st car = 224 miles / 3.5 hours
= 64 miles / hour
and speed of 2nd car = 175 miles / 3.5 hours
= 50 miles/ hour
We know that, Area of a Circle is given by : πR²
Where : R is the Radius of the Circle.
We can Notice that : The Given Figure is One - Fourth of the Circle with Radius 'R'
We can Notice that : The Quarter of the Circle is divided into 3 Equal Parts and The Shaded Region is One of the Equal Part.
Volume of cone : V=1/3pie r^2h
Answer:
10, 26, 74, 218, 650
Step-by-step explanation:
n * 3 - 4
Answer:
The answer to your question is 10 in
Step-by-step explanation:
Data
Circumference = 20π in
Radius = x
Formula
Circumference = πd
Process
1.- Equal the formula to the circumference
πd = 20π
2.- Solve for d
d = 20π / π
3.- Simplification
d = 20
4.- Find the radius
r = d/2
r = 20/2
r = 10 in
