Answer:
Step-by-step explanation:
The circumference of a circle is the distance around the circle.
The formula for determining the circumference of the circle is expressed as
Circumference = 2πr
If the circumference of the inner circle is 44ft, the radius of the inner circle would be
2πr = 44
2 × 3.14 × r = 44
r = 44/6.28 = 7
The radius of the outer circle would be 7 + 3 = 10ft
Therefore, the circumference of the outer circle would be
2 × 3.14 × 10 = 62.8 ft
The difference in the circumference of the inner circle and the outer circle is
62.8 - 44 = 18.8 ft
Answer:
160 cm
Step-by-step explanation:
a square has 4 equal sides. if one of the sides is 40 cm, then all of the other sides are 40 cm as well. to get a perimeter, you add up the lengths of all the sides. if there are 4 sides of 40 cm, you multiply 40 by 4 to get 160, finally add the unit to get 160 cm.
Answer:
Step-by-step explanation:
Given that
,
The weibull distribution with parameters
where
Then,
A) The probability that a specimen's lifetime is at most 250 is
The probability that the specimen's life time is more than 300 is
= 0.0992
b)The probability of the specimen's lifetime is between 100 and 250
c) The value such that exactly 50% of all specimens have lifetimes exceeding that value is
x = 192.07
I believe that would be, C=1.5(x)+5
X would be the about of toppings wanted on the pizza.
