32.25 cu. in.
Answer:
option 2nd is correct
volume of a cone is, 10.75 cubic inches
Step-by-step explanation:
Volume of a cone (V) is given by:
......[1]
where,
r is the radius of the cone and h is the height of the cone respectively.
As per the statement:
The volume of a cylinder is 32.25 cubic inches.
Volume of a cylinder is given by:
⇒
Divide both side by 3.14 we have;
It is also given that a cone has the same height and radius as the cylinder.
⇒ and
⇒
Using formula [1] we have;
Simplify:
cubic inches
therefore, volume of a cone is, 10.75 cubic inches
Answer:
Step-by-step explanation:
Since the box doesn't have the top, the total surface area includes 4 sides and the bottom.
Cardboard used is 1044 cm²
Answer:
a₁₆ = -
Step-by-step explanation:
there is a common difference between consecutive terms in the sequence, that is
- 1 = -
0 - = -
this indicates the sequence is arithmetic with nth term formula
= a₁ + d(n - 1)
where a₁ is the first term , d the common difference , n the term number
here a₁ = 1 , d = - , n = 16 , then
a₁₆ = 1 + (- × 15 ) = 1 + (- ) = - = -
There are 1.3 miles in 2,200 yards.
It is the conversion of one unit to another unit with its standard conversion.
Examples:
1 hour = 60 minutes
1 minute = 60 seconds
1 km = 1000 m
We have,
2,200 yards ____(1)
1 mile = 1760 yards _____(2)
Now,
From (1) and (2),
1 mile = 1760 yards
Multiply 2,200/1760 on both sides.
2,200/1760 x 1 mile = 2,200/1760 x 1760 yards
1.25 miles = 2,200 yards
Rounding to the nearest tenths.
1.3 miles = 2,200 yards
Thus,
There are 1.3 miles in 2,200 yards.

Answer:
1.25 mi
Step-by-step explanation:
First, we want to convert a yard into feet; recall 1 yard = 3 feet.
Then we want to divide that by the number of feet in a mile 1 mile = 5280feet.
So 2200*3 =6600, then divide by 5280
6600/5280 = 1.25 mi
2200 yard is 1.25 miles
