I think its A.
Step-by-step explanation:
Answer:
Option D) is correct
That is Option D) "The diagonals bisect each other" is correct
Step-by-step explanation:
The property of all squares is
"The diagonals of a square bisect its angles" and it can be written also also as below
"The diagonals bisect each other"
Therefore Option D) is correct
That is Option D) "The diagonals bisect each other" is correct
Answer:
A = 160 mm²
Step-by-step explanation:
The area (A) of a rectangle is calculated as
A = bh ( b is the base and h the height )
Given P = 52 and P = 2(b + h) , then
2(b + h) = 52 ( divide both sides by 2 )
b + h = 26 ( substitute b = 16 )
16 + h = 26 ( subtract 16 from both sides )
h = 10
Then
A = 16 × 10 = 160 mm²
Answer:
is there supposed to be a picture?
Step-by-step explanation:
Answer: figures C and D.
Explanation:
The question is which two figures have the same volume. Hence, you have to calculate the volumes of each figure until you find the two with the same volume.
1) Figure A. It is a slant cone.
Dimensions:
- slant height, l = 6 cm
- height, h: 5 cm
- base area, b: 20 cm²
The volume of a slant cone is the same as the volume of a regular cone if the height and radius of both cones are the same.
Formula: V = (1/3)(base area)(height) = (1/3)b·h
Calculations:
- V = (1/3)×20cm²×5cm = 100/3 cm³
2. Figure B. It is a right cylinder
Dimensions:
- base area, b: 20 cm²
- height, h: 6 cm
Formula: V = (base area)(height) = b·h
Calculations:
- V = 20 cm²· 6cm = 120 cm³
3. Figure C. It is a slant cylinder.
Dimensions:
- base area, b: 20 cm²
- slant height, l: 6 cm
- height, h: 5 cm
The volume of a slant cylinder is the same as the volume of a regular cylinder if the height and radius of both cylinders are the same.
Formula: V = (base area)(height) = b·h
Calculations:
- V = 20cm² · 5cm = 100 cm³
4. Fiigure D. It is a rectangular pyramid.
Dimensions:
- length, l: 6cm
- base area, b: 20 cm²
- height, h: 5 cm
Formula: V = (base area) (height) = b·h
Calculations:
- V = 20 cm² · 5 cm = 100 cm³
→ Now, you have found the two figures with the same volume: figure C and figure D. ←
