Answer:
54.22 mm
Step-by-step explanation:
Find the circumference of the circle and then divide it by 2.
We start with the formula for the circumference for the circle:
C = 2πr
To find r, divide 22 by 2:
22/2=11
Now find the cicumference:
C = 2πr = 2(3.14)(11) = 108.46 mm
NOW, to find the perimeter of the semicircle, divide the circumference by 2:
108.46/2 = 54.22 mm
All you do is multiply 300*.27=

The total surface area of the cone in terms of pi is 360π square inches
Total surface area of a cone is expressed as
TSA = πr(r+l)
Given that
radius = 10in
Height = 24in
Get the slant height 'l'
l² = h²+r²
l² = 24²+10²
l² = 576+100
l² = 676
l = 26in
Substitute the given values into the formula
TSA = pi(10)(10+26)
TSA = pi(36)(10)
TSA = 360π in²
Hence the total surface area of the cone in terms of pi is 360π square inches

Answer:
n=-8.86
Step-by-step explanation:
Slope will determine the direction and the steepness of a function. It could be either increasing/decreasing depend on minus or plus. The formula for slope is
m= (y2-y1)/ (x2-x1)
If you add (n,-6) and (-9,-4) to the equation, it will be:
m= (y2-y1)/ (x2-x1)
-15= (-6--4)/ (n--9)
-15= (-2)/ (n+9)
-15(n+9) = -2
-15n - 135=-2
-15n= -2 + 135
n= -133/15
n= -8 13/15= -8.86
