Which is closest to the surface area of a cone with dimensions as shown?
A. 113 mm2
B. 75 mm2
C. 66 mm2
D. 207 mm2
Answers
Answer:
B
Step-by-step explanation:
A=πr(r+h2+r2)=π·3·(3+42+32)≈75.39822
Answer:
75.39 mm²≈ 75 mm²
Step-by-step explanation:
A=πrl+πr²
l=[tex]\sqrt{r^2+h^2}[/tex]
A=πr(r+[tex]\sqrt{r^2+h^2}[/tex])=π·3·(3+[tex]\sqrt{4^2+3^2}[/tex])≈75.39 mm²
75.39 mm² ≈ 75 m²

Dennis and Eduardo are studying transformations using triangles. A ABC and A DEF are both plotted on a coordinate plane
Dennis notices that if he reflects A ABC across the y-axis and then translates it down 4 units, the result is A DEF.
Eduardo says that he can first translate A ABC down 4 units and then reflect it across the y-axis in order to get A DEF.
Is Eduardo correct? Explain your answer and tell whether A ABC and A DEF are congruent.
Type your answer in the box below.
Answers
Answer:
i think they are
Step-by-step explanation:
The translation of the 4 units right then a reflection across the x-axis will map triangle ABC onto triangle DEF.
What are the translation and reflections of an image?Translation of an image indicates the horizontal or vertical movement of that image. The reflection of an image indicates the mirror image of the given image along with a fixed-line.
Here, when we translate the triangle ABC to the right by 3 units, then point A will be at (2, 6), point B will be at (2, 3), and point C will be at (4, 3.).
Hence, after reflecting the triangle ABC, we get the triangle DEF.

y=-4/5x+2
Step-by-step explanation:
SORRY FOR THE LATE RESPONSE
slope-intercept form is y=mx+b
b is the y-intercept -> 2
m is the slope, which would be the rise/run -> -4/5
to identify the slope all you need to do is pick two points on the line, and find the direction of the line from left to right. rise/run basically means you find the distance going up and down first, and then the distance from left to right next.
now just put the equation together-> y=-4/5x+b

(b) Starting with the same cube, identify the two-dimensional shape of the cross-section if the cube is sliced vertically.
(c) Explain why the shapes are the same or different.
Answers
Answer:
a) square
b)square
c)they are the same thing because on all sides they are all the same length meaning the same shape
Step-by-step explanation:
If the cube is sliced horizontally, the cross-section will be a square and if the cube is sliced vertically, the cross-section will be a rectangle.
What is Three dimensional shape?A three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
(a) If the cube is sliced horizontally, the cross-section will be a square.
(b) If the cube is sliced vertically, the cross-section will be a rectangle.
(c) The shapes are different because the direction of the slice is different. Slicing horizontally means the slice is perpendicular to the vertical edges of the cube, resulting in a square cross-section.
Slicing vertically means the slice is perpendicular to the horizontal edges of the cube, resulting in a rectangular cross-section.
The dimensions and orientation of the cross-section depend on the orientation of the slice relative to the edges of the cube.
Hence, If the cube is sliced horizontally, the cross-section will be a square and if the cube is sliced vertically, the cross-section will be a rectangle.
