(a) Draw the net of a cube with sides 4 cm;

Lemur [1.5K]

A) draw a cube
i) 16cm
ii) 80 cm
b)64 cm
Ok so draw the outline of a cube with 4cm each. There is six sides and the area is just multiplying 4 by 4. So, since the area of each side is 16, and there is 6 sides, the surface area is 80 cm. The volume is just length x width x height (4x4x4) so it’s 64 cm cubed.

What is the value of r (3,4), (-1,r),m=-3/4

Llana [10]

To find the value of r

We will follow the steps below

Usinf the equation of a slope:

slope(m) =

$m=\frac{y_2-y_1}{x_2-x_1}$

from the question given;

m= -3/4

x₁ = 3

y₁=4

x₂=-1

y₂=r

substituting the values into the slope formula

$\frac{-3}{4}\text{ = }\frac{r-4}{-1-3}$

we can now simplify and then solve for r

$\frac{-3}{4}\text{ = }\frac{r-4}{-4}$

cross-multiply

-3 x -4 = 4(r-4)

12 = 4(r-4)

Divide both-side of the equation by 4

$\frac{12}{4}\text{ = }\frac{4(r-4)}{4}$

3 = r - 4

add 4 to both-side of the equation

3+4 = r-4+4

7 = r

r=7

Therefore the value of r is 7
