Find the curcumince of the circle. use 3.14 or 22/7.
Answer:
the circumference of this circle is approximately 25.12 cm with π as 3.14.
Step-by-step explanation:
circumference of a circle is technically a perimeter of a circle.
we find the circumference of a circle by using the following formula :
c = 2πr or c = πd
r represents the radius d represents the diameter
since 4 yds here is a radius, we use the left formula i placed above. then, we substitute the numbers in. pi represents 3.14 as said in your question. even if you use 22/7, you will still get around the same result.
c = 2πr
c = 2(3.14)4
c = 6.28(4)
c = 25.12 yds
therefore, the circumference of this circle is approximately 25.12 yds.

Step-by-step explanation:
Where is the midpoint of AB if A(6, 4) and B(5,-2)?
A) (11,2)
B (11,6)
C) (5.5,3)
D (5.5,1)
Answer:
Step-by-step explanation:
The midpoint is just the average coordinates of the endpoints.
mp=((x1+x2)/2, (y1+y2)/2), we have points (6,4) and (5,-2)
mp=((6+5)/2, (4-2)/2)
mp=(5.5, 1)
So D is the answer.
What is the formula used to find the area of this
shape? *This symbol: / means divided by
A= b xh/2
A= I xw
A=s2
A= (b1 +b2)h/ 2
Answer:
A = (b1 + b2)h/2
Step-by-step explanation:
The shape given is a trapezoid having two parallel sides which can be labelled b1 and b2 respectively. The distance between the two parallel sides is the height of the trapezoid, which is labelled h.
Area of a trapezoid is given as:
A = (b1 + b2)h/2

1. Leslie visits a local department store in order to purchase summer clothes. The
price of the dress is $40. The dress is marked up 25%. What is the selling price of
the dress?
Answer:
$50
Step-by-step explanation:
Given data
We are given that the price is $40
the markup percent is 25%
Hence the price will be
40+25% of 40
=40+ 25/100*40
=40+ 0.25*40
=40+10
=$50
Therefore, the price of the dress is $50

Answer:
∠H = 50°∠A = 80°∠W = 130°Step-by-step explanation:
It is helpful to remember that opposite angles of an inscribed quadrilateral are supplementary. This lets you find the value of m.
∠A +∠K = 180°
8m° +10m° = 180°
18m = 180
m = 180/18 = 10
Using this value we can find ...
∠H = 5m° = 5·10° = 50°
∠A = 8m° = 8·10° = 80°
∠W = 180° -∠H = 180° -50° = 130°

A piece of rural land sold ten years ago for 40000. The price for the same land this year is $800 more per acre, and it sold for 60000. What is the size of the piece of land in acres?
Answer: 25
Step-by-step explanation:
From the question, we are informed that the piece of rural land sold ten years ago for 40000 and that the price for the same land this year is $800 more per acre, and it sold for 60000.
The size of the piece of land in acres will then be:
40000 + 800x = 60000
800x = 60000 - 40000
800x = 20000
x = 20000/800
x = 25
The land is 25 acres
Answer: 25
Step-by-step explanation:
40000 + 800x = 60000800x = 60000 - 40000800x = 20000x = 20000/800x = 25
What is the approximate Probability of drawing a Black OR Face Card from a standard deck of shuffled cards?
Answer:
0.73
Step-by-step explanation:
Number of cards in a standard deck = 52
Number of black cards = 26
Number of face cards = 12
Probability of drawing either a black or face card
Probability = required outcome / Total possible outcomes
P(drawing a black card or face card) = (number of black cards / total card) + (number of face cards / total cards)
= 26/52 + 12 /52
= 0.5 + 0.2307692
= 0.73

A circle has a secant and a tangent that intersect outside of the circle. If the measure of ∠ is 29° and the measure of is 45°, then determine the measure of
Answer:
CD = 103°
Step-by-step explanation:
The secant- tangent angle BAD is half the difference of the intercepted arcs, that is
[tex]\frac{1}{2}[/tex] ( CD - BD ) = 29° ( multiply both sides by 2 )
CD - BD = 58°
CD - 45° = 58° ( add 45° to both sides )
CD = 103°
