Answer:
Step-by-step explanation:
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Where
r represents the radius of the cylinder.
h represents the height of the cylinder.
π is a constant whose value is 3.14
From the information given,
Height = 19 cm
Since the base area is 24π cm², we would determine its radius by applying the formula,
Area of circle = πr²
24π = πr²
r² = 24
r = √24
Therefore,
Volume of cylinder = π × (√24)² × 19 = 456π cm³
It is approximately
456 × 3.14 = 1431.8 cm³
The answer to number 3 is -12 because you would do X times 4 and then add 8
the answer to number 4 is 46 because you would do X times 3 and then add 7
Answer:
if -5n+7<57, then n>-10.
if 6n+2<8, then n<1.
Step-by-step explanation:
-5n+7<57
1. subtract 7 from both sides:
-5n+7 -7< 57 -7
-5n<50
2. divide both sides by -5 (remember to flip the sign whenever you divide by a negative number):
-5n ÷-5<50 ÷-5
n>-10
6n+2<8
1. subtract 2 from both sides:
6n+2 -2<8 -2
6n<6
2. divide both sides by 6:
6n ÷6<6 ÷6
n<1
<u>Statement</u><u>:</u>
The circle has a diameter of 16 inches.
<u>To </u><u>find </u><u>out:</u>
The area of the circle.
<u>Solution</u><u>:</u>
- Diameter of the circle = 16 inches.
- Radius of the circle
- = Diameter ÷ 2
- = 16 inches ÷ 2
- = 8 inches
- We know, area of a circle = πr² where r is the radius.
- Therefore, the area of the circle
- = 3.14 × (8)² square inches
- = 3.14 × 64 square inches
- = 200.96 square inches
- = 201 square inches [rounded to the nearest square inch]
<u>Answer</u><u>:</u>
C) 201 square inches
