Qi. calculate the thickness of a disc of<br>a diameter 14cm and Surface area<br>is 3cm?
Firdavs [7]

Answer:

Thickens (Height) = 0.068 cm

Step-by-step explanation:

Given:

Diameter of disc = 14 cm

Radius of disc = 14 / 2 = 7 cm

Surface area = 3 cm²

Find:

Thickens (Height)

Computation:

Disc is a cylinder in shape

Surface area = 2πrh

3 = 2(22/7)(h)(7)

3 = 44(h)

Thickens (Height) = 0.068 cm

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 18 cm3
Minchanka [31]

Answer:

12 cm³

Step-by-step explanation:

Let's say the radius of the sphere and cylinder is r and the height is h. However, notice that the "height" of the sphere is the same thing as the diameter, which is 2r, so h = 2r.

The volume of a sphere is denoted by: V=\frac{4}{3} \pi r^3 , where r is the radius.

The volume of a cylinder is denoted by: V=\pi r^2h, where r is the radius and h is the height. Plug in 2r for h and 18 for V:

V=\pi r^2h

18=\pi r^2*2r=2\pi r^3

\pi r^3=18/2=9

Now plug in 9 for πr³ in the volume formula for the sphere:

V=\frac{4}{3} \pi r^3

V=\frac{4}{3} *9=12

The volume of the sphere is 12 cm³.

The function h ( t ) = − 3t 2 + 12 t + 63 models the flight of a ball t seconds after it is thrown. When can the ball be expecte
Oksana_A [137]

As the ball hits the ground, its height will be equal to 0, so...

-3t² + 12t + 63 = 0

t² - 4t - 21 = 0

Using the Viet's theorem to solve the quadratic equation quicker:

t₁ + t₂ = 4

t₁t₂ = -21

t₁ = -3 - this is not possible because time can't be negative

t₂ = 7

That means, the ball is expected to hit the ground after 7 sec has passed.
