Answer:
a) Circumference of the circle = 56.52 in
b) Area of the circle = 254.34 in²
Step-by-step explanation:
Mr. Bernard needs to order boxes for his 18-inch diameter "Super Pizza."
Note that:
Pizza is Circular in shape
a) What is the approximate circumference of the Super Pizza? Use 3.14 for π. Show your work.
The formula for the circumference of a circle when given that diameter = πD
Where D = Diameter of the circle = 18 in
π = 3.14
Hence,
Circumference of the circle = 3.14 × 18 in
= 56.52 in
b) What is the approximate area of the Super Pizza? Use 3.14 for π. Show your work.
The formula for the area of a circle = πr²
Radius = Diameter/2
Diameter = 18 in
Radius = 18 in/2 = 9 in
The area of the circle = 3.14 × 9²
= 254.34 in²
Given
The formula for the sum of an infinite geometric series
used to convert 0.23 to a fraction
Find out the values of a1 and r
To proof
As given in the question
The series is infinte geometric series
The geometric is mostly in the form a , ar , ar² ,............
s = a + ar + ar² + ar³...........
Where a = first term
r = common ratio
The series is infinte geometric series i.e 0.2323...
thus it is written in the form
s = 0.23 + 0.0023 + 0.000023 +...........
now written in the fraction form
we get
compare this series with the
s = a + ar + ar² + ar³...........
Thus
we get
a1 = 0.23
r = 0.01
Hence proved
Answer:
X=35
You have to simply the equation using cross multiplication, divide by both sidesof the equatiom by 2 and move the constant to the right and change its sign. Then add the numbers. I hope this helped :)
The labeled point means the Amelia biked 1.5 30 miles in 1.5 hours.
This means that in 1 hour, Amelia biked 20 miles.
Her distance changed at a unit rate of 20 miles per hour, so that was her speed.
Answer:
the answer is C)
Step-by-step explanation:
This is because when you look at the sides you have to find pairs of smallest to greatest
