What is the volume of the cone?​

Mathematics
1 answer:
lina2011 [118]3 years ago
6 0

Answer:

The volume of the cone is 75.36 cm³

Step-by-step explanation:

The rule of the volume of a cone is V = \frac{1}{3} π r² h, where

  • r is the length of the radius of its base
  • h is the height of the cone

In the given figure

∵ The length of the radius of the cone is 3 cm

∴ r = 3 cm

∵ The length of the height of the cone is 8 cm

∴ h = 8 cm

→ Substitute the values of r and h in the rule of the volume above

∵ π ≅ 3.14

∵ V = \frac{1}{3} (3.14)(3)²(8)

∴ V = 75.36 cm³

∴ The volume of the cone is 75.36 cm³

Answer:

x=3 and y= 4 / 3 (Fraction)

Step-by-step explanation:

Substitute x for 6y-5.

2(6y−5)−3y=2

Add 6y and 3y, and multiply 5 by 2/Simplify the equation.

9y−10=2

Add  10 to both sides, and then divide each side by 9.

9y−10+10=2+10

9y / 9 = 12 / 9

y = 4/3.

Repeat the process but replace y with 4/3!

Of course for a rectangle A = L × W and we need to be careful about the units.

Here that's

18900 sq cm = L × 180 cm

where the area's in sq cm so we converted the width.  We get

L = 18900 / 180 =  105 cm

We're asked for the result in meters, so that's

Answer: 1.05 m

The perimeter of the outer rectangle is

18.4 m + 32.5 m + 18.4 m + 32.5 m = 101.8 m

Answer: 101.8 m

The area of the seating space is the big rectangle minus the small rectangle,

A = 18.4(32.5) - 15(28) = 178 sq m

Answer: 178 sq m

PLEASE HELP ! The total const after tax to repair Kimber's cracked phone screen is represented by 0.04h(30h)+t here h represents
goblinko [34]

okay, i have to be honest, this equation is a little tricky because the use of "h" is kind of weird, using it twice to show...what exactly i am not too sure.

the answer:

The variable "t" is the amount of taxes she has to pay for repairing her cracked phone. "t" is shown as an extra amount of money to pay, and since it does not state that taxes were dependent on the amount of time it took to repair the phone, it must have been a fixed price. The amount of money it takes to repair the phone (tax not included) is shown to be dependent on time, though.
