The area of a circle is the radius squared x pi.
Area = r^2 x pi
R is the radius which is half the diameter.
Diameter = 102 inches
Radius = 102/2 = 51 inches
Area = 51^2 x pi
Area = 2,601pi inches^2 ( in terms of pi) or
Area = 8,167.14 inches^2
Area of circle is 8,167.14 cm ²
Step-by-step explanation:We have
diameter of circle = 102 cm
And we need to find area of circle,
So the formula we using is
Area of circle = π ×r ²
Here,
R denotes for Radius
π denotes for pi.
For finding area of circle we need to find radius
here we have diameter of circle = 102 cm and
We know that ,diameter is the double of radius it means radius is the half of diameter
So, radius of circle = 102/2 = 51 cm
Now Solve it
Area of circle = π × ( r ) ²
Substitute the value
Area of circle = 3.14 × ( 51cm )² .. [ using π = 3.14 ]
Multiply the values
Area of circle = 3.14 × ( 51 cm × 51cm) ..[( 51 ) ²= 51 × 51]
Area of circle = 3.14 × 2,601 cm².
Therefore , Area of circle is 8,167.14 cm ²

Answer:
half of 45.7 is 22.85
22.85^2 = 522.1225
522.1225 x pi
Meaning
522.1225π, A
Answer:
[tex]522.12\pi[/tex] inches²
Step-by-step explanation:
The formula for finding the area of a circle is:
[tex]A=\pi r^2[/tex]
If you put 45.7/2 (because you have the diameter and NOT the radius) instead of r you get:
[tex]A=22.85^2\pi[/tex]
Now you calculate:
[tex]A=522.12\pi \\[/tex] inches²

Tulsa has 4 times as many mangoes as Julie. Tulsa bought 6 more mangoes. She now has 5 time as many mangoes as Julie . How many many mangoes Tulsa had at first
Answer:
24
Step-by-step explanation:
Let the number of mangoes owned by Tulsa be T and that by Julie be J
If Tulsa has 4 times as many mangoes as Julie then
T = 4J
Tulsa bought 6 more mangoes. She now has 5 time as many mangoes as Julie
T + 6 = 5J
Solve both equations simultaneously by substitution
4J + 6 = 5J
Collect like terms
6 = 5J- 4J
J = 6
Since
T = 4J
T = 4 * 6
= 24
Hence Tulsa had 24 mangoes at first
What are the coordinates for point D?

Step-by-step explanation:
Please help me with this one no links
Answer:
L' = (0, 1 )
Step-by-step explanation:
The translation rule
(x, y ) → (x - 2, y - 1 )
Means subtract 2 from the x- coordinate and subtract 1 from the y- coordinate.
L (2, 2 ) → L' (2 - 2, 2 - 1 ) → L' (0, 1 )
The length of a rectangle is 8 cm. Its diagonal measures 14
cm. What is its width?
Answer:
width is 2√33 cm
Step-by-step explanation:
you will make a right triangle with hypothenuse 14 , one side 8 and the other side x is the width.
use Pythagorean Th.
14² = 8² + x²
x² = 14² -8²
x² = 132
x = √132 = 2√33

Here is part of a timetable for the Paris to Montpellier express train service.
The average speed of the 20 07 train from Paris is 224 km/h. Work out the distance this train travels from Paris to Montpelli
Answer:
772.8 km
Step-by-step explanation:
Speed is the rate of change of distance. Speed is the ratio of distance travelled to time taken. Average speed is the ratio of the total distance travelled to the total time taken, it is given by:
Average speed = Total distance / total time
The 20 07 train leaves Paris at 20:07 and reaches Montpellier at 23:34. This means that the total time taken is 3 hours 27 minutes, that is 3.45 hours.
Given that average speed is 224 km/h, hence:
Average speed = total distance / total time
224 km/h = total distance / 3.45 h
total distance = 224 * 3.45 = 772.8 km
Can someone explain to me how the Pythagorean theorem works??
Answer:
By the Pythagorean theorem, it follows that the hypotenuse of this triangle has length c = √a2 + b2, the same as the hypotenuse of the first triangle. Since both triangles' sides are the same lengths a, b and c, the triangles are congruent and must have the same angles. ... If a2 + b2 = c2, then the triangle is right.
Step-by-step explanation:
Solve for the value of x.
Step-by-step explanation:
9x-4+6x+4=180 ( being straight angle)
15x=180
x=180/15
x=12
I hope it help you
plz answer, will give brainliest
Answer:
12
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + 9^2 = 15^2
a^2 +81 =225
Subtract 81 from each side
a^2 = 225-81
a^2 = 144
Take the square root of each side
sqrt(a^2) = sqrt(144)
a=12
Answer:
a = 12 meters
Step-by-step explanation:
Use pythagorean theorem to identify the missing leg
pythagorean theorem = [tex]a^2+b^2=c^2[/tex]
In this case, we are looking for a so...
[tex]a^2+b^2=c^2[/tex]
[tex]a^2+9^2=15^2[/tex]
[tex]a^2+81=225[/tex]
[tex]a^2=225-81[/tex]
[tex]a^2=144[/tex]
It doesn't make sense for a to be equal to 144 so we must square root 144
144 = [tex]12^{2}[/tex] meters
Final Answer: 12 meters

Marta is building a scale model of the Empire State building which has a rectangular base. The scale on the model is 1 inch = 35 feet. Her model is 4 inches in length and 1 inch in width. What is the actual area, in square feet, of the base of the building?
Answer: The actual area of the base of the building is 4900 square feet.
Step-by-step explanation:
We have given, the scale on the model: 1 inch = 35 feet
In model,
Length= 4 feet , Width = 1 inch
As per scale ,
Actual length = 4 x 35 feet
= 140 feet
Actual width = 35 feet
Area of base of the building = Length x width
= 140 x 35
= 4900 square feet
Hence, the actual area of the base of the building is 4900 square feet.
Mohammed pays $569.80 for a mountain bike in a sale, the original price had been reduced by 26%, calculate the original price of the mountain bike
Answer:
$770
Step-by-step explanation:
26% off means the Mohammed paid 74% of the original price.
0.74x=569.80
x=569.8/0.74
x=770
proof:
770*0.26=200.2
770-200.2=569.8
How do I find the Q1 and Q3?
0,0,1,2,2,3,4,4,4,4,5,6,6,7,7
Answer:
Q1 = 2
Q3 = 6
Step-by-step explanation:
Mathematically, we have
Q1 = (n + 1)/4 th term
where n is the number of terms
By the count, we have n as 15
Q1 = (15 + 1)/4
Q1 = 4th term
Looking at the arrangement, the 4th term is 2
For Q3
Q3 = 3(n + 1)/4 th term
n = 15
Q3 = 3 * 4 = 12th term
The 12th term is 6
So that is the 3rd quartile
