Answer:
73.4 cm^2
Step-by-step explanation:
The equation is :
πr^2
Substitute the radius in:
π(5)^2
Solve:
Area of full circle = 25π
(Note : leave this answer in terms of 'pi' so it is easier to handle
Next, find the area of the sector
The equation for this is:
(angle/360) x πr^2
Substitute the values in:
(80/360) x π(5)^2
Solve :
Area of sector = (50/9)π
Now, find the area of the triangle:
1/2 absinC
Substitute the values in:
1/2(5)(5) x sin(80) = 12.31009691
Subtract this answer from the area of the sector
Answer = 5.14319607
Subtract this from the area of the whole circle
Answer = 73.39662073
To the nearest tenth, that would be 73.4 cm^2

Answer: y = -1x + 8
Step-by-step explanation: linear equations must be written in the format
y = mx + b from.
m represents the slope which it -1
b represents the y-intercept which is 8.
Just substitute the slope and y-intercept in the m and b places and that is a linear equation.

Now we have
29 x 180 / 18
29 x 180 = 5220
5220 / 18

Answer:
Step-by-step explanation:
Smaller values of the standard deviation result in a normal curve that is narrower and more peaked.
Answer:
32.841 megabytes
Step-by-step explanation:
To find how many were downloaded, multiply 267 by 0.123
267(0.123)
= 32.841
So, 32.841 megabytes have been downloaded
