Find the distance between the points (0,-2) and (6,-6)

goldenfox [79]

Answer:

Formular:

$length = \sqrt{ {(x_{1} - x_{2} )}^{2} + {(y_{1} - y_{2} ) }^{2} }$

x1 » 0

x2 » 6

y1 » -2

y2 » -6

$l = \sqrt{ {(0 - 6)}^{2} + {( - 2 - 6)}^{2} } \\ \\ l = \sqrt{ {( - 6)}^{2} + {( - 8)}^{2} } \\ \\ l = \sqrt{36 + 64} \\ \\ l = \sqrt{100}$

for the √100 in surds:

$l = \sqrt{10 \times 10} = \sqrt{ {10}^{2} } = ( {10}^{2} ) {}^{ \frac{1}{2} } \\ \\ { \boxed{ \boxed{distance = 10 \: \: units}}}$

A rectangular box has length 20cm, width 6cm and height 4cm. find how many cubes of size 2cm that will fit into the box.

Papessa [141]

Answer:

$\boxed{\pink{\sf The \ number \ of \ cubes \ that \ can \ be \ fitted \ is 60 .}}$

Step-by-step explanation:

Given dimensions of the box = 20cm × 6cm × 4cm .

Dimension of the cube = 2cm × 2cm × 2cm .

Therefore the number of cubes that can be fitted into the box will be equal to the Volume of box divided by the Volume of the cube. So ,

$\boxed{\red{\bf \implies No. \ of \ cubes \ = \dfrac{Volume \ of \ box}{Volume \ of \ cube }}}$

$\bf \implies n_{cubes} = \dfrac{20cm \times 6cm \times 4cm .}{2cm \times 2cm \times 2cm } \\\\\bf\implies n_{cubes} = 10 \ times 3cm \times 2cm \\\\\implies \boxed{\bf n_{cubes}= 60 }$

<h3>Hence the number of cubes that can be fitted in the box is 60 .</h3>

What is the surface area of the cone to the nearest whole number? Use 3.14 for π.

IRISSAK [1]

Hello!

We know that surface area of a cone = pi(r^2) + pi(rL) where L is the Slant height and R is the Radius and h is Height.
So, 30 is height, and half of 32 is the radius, then we just plug and chug,

An in Short, Your Answer would be 2512, Option "A"

Hope this Helps! :)
