Answer:
I am attaching a image to understand my proof.
Step-by-step explanation:
PROVE:-
AB = DC
AD = BC
∠ ABD = ∠ BDC (alternate angles are equal )
∠ DBC = ∠ ADB (alternate angles are equal )
∴ Δ ADB ≅ Δ CBD ( by ASA rule )
DC = BA ( corresponding sides of ≅ Δ )
AD = CB ( corresponding sides of ≅ Δ )
Hence it is proved that opposite sides of parallelogram are congruent )
Answer:
Step-by-step explanation:
Hey there!
The formula for the volume of a cone is .
In this cone, we have the given information:
The information we need for this formula is the radius and height.
We already have the height, but not the radius.
Fortunately, we can easily get it by dividing the diameter by 2.
So, the radius is 2.
Let 3.14 be .
Plug in each value into the equation.
Simplify the exponent and fraction.
Multiply the three numbers together.
But wait! We have to round this to the nearest tenth.
When rounding, we look at the place value one less than the one we are rounding to. Since we are rounding to the nearest tenth, we look at the hundredths place, which is the digit 2.
Since 2 is less than 5, we round down to 25.1.
This is the volume of a cube, and it is measured in inches, so the unit we will use is .
So, your <u>final answer</u> is !
Hope this helps!
