If this is suggesting circumference then you would use the equation pi(d). You can round off pi to 3.14 and substitute in the diameter of the circle in the equation: 3.14(75)=235.5 which then rounded would equal 236. Circumference also refers to if you would cut the circle so that it was a line segment, in meaning the entire measurement of the circle around.
Radius = Diameter ÷ 2
Radius = 6 ÷ 2 = 3cm
Surface area = 2πr² + 2πrh
Surface area = 2 π (3)² + 2 π (3) (11.5) = 272.32 cm² (nearest hundredth)
Answer: 272.32 cm²
The answer is 21 because 9+10=21 see im smart
Answer:
14 units
Step-by-step explanation:
We apply the <em>Theorem of reflection over parallel lines.</em>
Theorem: The composition of two reflections over parallel lines that are h units apart is the same as a translation of 2h units.
Given that the two parallel lines are 7 units apart
h=7 units
2h= 2 X 7 =14 units
Therefore, the preimage and the final image will be 14 units apart.
Answers:
A''(3, 0); B''(3, 2); C''(1, 1); D''(1, -1)
Explanation:
We perform the reflection across y=x first. This reflection switches the x- and y-coordinates; this maps:
A(2, 4)→A'(4, 2)
B(4, 4)→B'(4, 4)
C(3, 2)→C'(2, 3)
D(1, 2)→D'(2, 1)
Next we perform the translation. This translation shifts the figure 1 unit left and 2 units down, by subtracting 1 from the x-coordinate and 2 from the y-coordinate. This maps:
A'(4, 2)→A''(3, 0)
B'(4, 4)→B''(3, 2)
C'(2, 3)→C''(1, 1)
D'(2, 1)→D''(1, -1)
