It’s A
Explanation: because it’s A
Answer:
654 1/2 cm³
Step-by-step explanation:
First the volume of the cylinder, the formula for that is πr²h
Radius is half of diameter so 7/2=3.5
3.5^2=12.25
12.25x22/7=38.5
38.5x15=577.5
Now the cone, the formula for this is πr²h/3
It has the same radius as the cylinder so 3.5^2=12.25
12.25x22/7=38.5
38.5x6=231
231/3=77
Now we add them together to find total volume.
577.5+77=654.5
Answer: 5 cm
Step-by-step explanation:
The diagonals of a rhombus bisect each other in half
PO = OR = 4 cm
So. PR = 8 cm
Similarly,
SO = OQ = 3 cm
So, SQ = 6 cm
To measure side, formula is
a = √p^2 + q^2 / 2
a = √6^2 + 8^2 / 2
a = √36+64 / 2
a = √100 / 2
a = 10/2 = 5 cm
I believe the answer is 128.2
