Answer:
550 miles
Step-by-step explanation:
A smooth curve which approximates the shape of a histogram and describes the overall pattern of a distribution is called density curve. A density curve is a graph that shows probability. The area under the density curve is equal to 100 percent of all probabilities and can be a skewed distribution. The right or left skew does not refer to how the graph looks but it refers to whether the data is skewed.
Answer:
Exact Circumference = 3π feet
Approximate Circumference = 9.42 feet
Exact Area = 2.25 π ft²
Approximate Area = 7.07 ft²
Step-by-step explanation:
Diameter = d = 3 feet
Radius = r = 1.5 feet
<u><em>Circumference:</em></u>
Outline of the pit is the circumference.
=> Circumference = 
Where d = 3 feet
=> <u>Exact Circumference = 3π feet</u>
=> <u>Approximate Circumference = 9.42 feet</u>
<u><em>Area:</em></u>
Area of Circle = πr²
Area = π(1.5)²
<u>Exact Area = 2.25 π ft²</u>
<u>Approximate Area = 7.07 ft²</u>
Answer:
solve it yourself
Step-by-step explanation:
length of ist part= 30 cm
breadth of ist part = 21 cm
area of ist part = 630 cm
diameter of 2nd part= 21 cm
area of 2nd part = ¼dπ
π= 22/7
= ¼× 21 ×22/7
=3×10.5
= 31.5cm²
total area = ist part +2nd part + 3rd part
=
Answer: -4y + 4
Step-by-step explanation: 12 + 3y - 8 - 7y
12 + 3y + -8 + -7y
(3y + -7y) + (12 + -8)
= -4y + 4
