Find the surface area of the cylinder in terms of π. 8 cm diameter and 17 cm height

JulsSmile [24]

Answer:
168pi cm2

Explanation:
SA = 2pi(r^2) + 2pi(r)h
diameter is 8 cm so radius is 4 cm
SA = 2pi(4^2) + 2pi(4)17
SA = 32pi + 136pi
SA = 168pi cm2

The two triangles

son4ous [18]

Solution:

Note that:

(3x)/20 = (4x + 2)/28

Using cross multiplication:

(3x)/20 = (4x + 2)/28
=> (3x) × 28 = (4x + 2) × 20

Simplifying both sides:

=> 84x = 80x + 40

Subtracting 80x both sides:

84x = 80x + 40
=> 84x - 80x = 80x + 40 - 80x

Simplify the LHS:

=> 84x - 80x = 40
=> 4x = 40
=> x = 10

I am at the Kruger National Park in Skukuza with the latitude and longitude coordinates (-24.98,31.58). My friends are exploring

Given Kruger National Park in Skukuza coordinate : (-24.98,31.58).

Nelson Mandela Musuem in Mpumalanga coordinate : (-29.82,31.58).

We need to find exactly in between given coordinates.

We know, mid - point formula :

$\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right).$

$\left(x_1,\:y_1\right)=\left(-24.98,\:31.58\right),\:\left(x_2,\:y_2\right)=\left(-29.82,\:31.58\right)$

$=\left(\frac{-29.82-24.98}{2},\:\frac{31.58+31.58}{2}\right)$ .

$=\left(-27.4,\:31.58\right)$ .

Therefore, will be meeting at (-27.4, 31.58).
