Answer: 267.95 cm^3

Step-by-step explanation:

diameter= 8 cm\\radius= \frac{d}{2}=\frac{8}{2} = 4 \\height= 4d\\\pi = 3.14

Formula: V=\frac{1}{3}\pi r^2h

V=\frac{1}{3}(3.14)(4)^2(16)\\V=\frac{1}{3}(3.14)(16)(16)\\V=267.95cm^3

Question 1 of 10
Anestetic [448]

Answer:

In a 30-60-90 triangle, the hypotenuse (or diagonal) times .5 equals the short side or the width (height) of the tv.

width or height = 15

and the "medium" side = 30 * (sqrt (3) /2).

medium side = 30 * (1.732 / 2)

medium side = 30 * .866

medium side (or width)= 25.98

so the exact width and height is:

width = 25.98

height = 15

What is the area of a circle if the circumference is 29
Kruka [31]

Answer:

67 square units

Step-by-step explanation:

Circumference/pi = diameter

29/3.14 = 9.24

Radius = 9.24/2 = 4.62

A = pi * r^2

A = 3.14 * 4.62^2 = 67 square units

A chemist has two solutions: a 50% methane solution and an 80% methane solution. He wants 100 mL of a 70% methane solution. How
Likurg_2 [28]

Answer:

33.33 mL of 50%

66.67 of 80%

Step-by-step explanation:

Let x = quantity of 50% methane.

Then,

0.50x + 0.80(100 - x) = 100 × 0.70

⇒ 0.50 x + 80 - 0.80 x = 70

⇒ -0.30 x = 70 - 80

⇒ -0.30 x = -10

⇒ x=\frac{10}{0.3}

⇒ x = 33.33 mL of 50%

and, 100 - 33.33 = 66.67 of 80%
