Answer:
153.86 cm^2
or
154 cm^2 (if you round it up)
Things to keep in mind:
R - Radius
A - Area
Pi = 3.14
Step-by-step explanation:
A = Pi * R^2 = 3.14 * 7^2 = 3.14 * 49 = 153.86 (cm^2)
Answer:
Its x^2 over 81 + y^2 over 18 = 1
major: (9,0) and (-9,0)
minor: (0,4.24) and (0,-4.24)

Answer:
Step-by-step explanation:
Total pink triangles = 24
Let first 10 triangles be a circle
let second ten triangles be a square
⇒ red circle = 10 triangles
⇒blue square = 10 triangles
Remaining triangles = 4
Thus circle+square+4 triangles=10+10+4
=24
Refer the attached figure.
This is a quick picture to show 24 after you have regrouped 1 ten as 10 ones
Answer:
To know if Nicholas is correct
4(540π) inches³ ≥ 2304π inches³
Unfortunately, 2160π inches³ is less than 2304π inches³. This means Nicholas is absolutely wrong .4 times the volume of the cylindrical bucket is less than the volume of the spherical tank.
Step-by-step explanation:
The question wants you to look for the volume of the cylindrical bucket and the spherical bucket and know if 4 times the volume of the cylindrical bucket will fill the spherical tank.
volume of a cylinder = πr²h
where
r = 6 inches
h = 15 inches
volume of the cylinder bucket = πr²h
volume of the cylinder bucket= π × 6² × 15
volume of the cylinder bucket = π × 36 × 15
volume of the cylinder bucket = 540π inches³
volume of the spherical storage container
volume = 4/3πr³
r = 24/2 = 12 inches
volume = 4/3 × π × 12³
volume = 4/3 × π × 1728
volume = 6912π/3
volume = 2304π inches³
To know if Nicholas is correct 4(540π) inches³ ≥ 2304π inches³
Unfortunately, 2160π inches³ is less than 2304π inches³. This means Nicholas is absolutely wrong .4 times the volume of the cylindrical bucket is less than the volume of the spherical tank.
