Answer:
14.13 m^2
Step-by-step explanation:
Formula for area:
3.14*r^2
To find the radius(r), you do diameter(d)/2:
9/2=4.5
3.14*4.5^2=14.13 m2
Answer:
Step-by-step explanation:
The point slope form of a straight line is expressed as
y - y1 = m(x - x1)
Where
m represents slope of the line
y1 represents the initial value of y
x1 represents the initial value of x
If two lines are parallel, it means that they have the same slope. From the equation of the given line, slope = 1/2
Therefore,
m = 1/2
x1 = - 3
y1 = - 2
Substituting into the point slope equation, it becomes
y - - 2 = 1/2(x - - 3)
y + 2 = 1/2(x + 3)
The equation is
y + 2 = 1/2(x + 3)
Each trianglar side has an area: (1/2)*8*9=36
the base is a square with an area of 8*8=64
so the total surface area is 36+36+36+36+64=208
Answer:
-15
Step-by-step explanation:
the new temperature since it went down
-12-3= -15
Total distance from w to z is -10 to 6 = 16
Add the ratios: 2 + 3 + 3 = 8
Divide distance by total ratio: 16/8 = 2
Multiply each ratio by 2 : 2x 2 = 4, 3 x 2 = 6, 3 x 2 = 6
WX is 4 units apart, add 4 to -10 to get x = -6
Answer: A. -6
