Answer:
50.265448
Step-by-step explanation:
Not sure what you mean by dot product, maybe explain and I can help better but the two make an equation of y= 4/1 x + -27, that is the equation of the line.
Answer:
m∠CGF=25°
Step-by-step explanation:
we know that
In a circle, a radius that bisects a chord is perpendicular to the chord
so
CS is perpendicular to AC
The triangle GFC is a right triangle
Remember that the sum of the measures of the interior angles in a triangle must be equal to 180 degrees
m∠CGF+m∠GFC+m∠GCF=180°
we have
m∠GFC=90°
m∠GCF=65°
substitute
m∠CGF+90°+65°=180°
m∠CGF+155°=180°
m∠CGF=180°-155°
m∠CGF=25°
Answer:
r = 18 cm
Step-by-step explanation:
The formula for the circumference of a circle is 2πr.
Hence,
2πr = 36π
r = 18 cm
Hey there!
In this problem, we'll just be finding the surface area of a rectangular prism. In this example, a surface area is a sum of all the areas of each individual face. On this rectangular prism, we have 6 faces, and two of each kind. Our formula is:
SA = 2(lw + wh + lh)
Notice how it has a 2. That two is because those two variables just applies for one side, and there's two for each type of side. On this diagram, the rightmost side's area would be the width (32) times the height (49) and the product would be the area. Let's plug in our numbers:
SA = 2(41 * 32 + 32*49 + 41*49)
Multiply:
SA = 2( 1312 + 1568 + 2009) =
Add:
SA = 2(2880 + 2009)
SA = 2(4889)
SA = 9778 ft squared, or C.
Hope this helps!
