Answer:

60 sq in

Step-by-step explanation:

Perimeter = 2l + 2w

If l = w+4

Perimeter = 2(w+4) + 2w

Perimeter = 4w+8

32 = 4w + 8

24 = 4w

6 = w

If w = 6, l = 6+4 = 10

Area = l * w

Area = 10 * 6

Area = 60

Write the equation of the line that passes through (-3,5) and (2, 10) in slope-intercept form.

cupoosta [38]

Answer:

$y=x+8$

Step-by-step explanation:

Slope of straight line can be calculated as

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

Here $(x_1, y_1)=(-3, 5) \ and \ (x_2, y_2) = (2, 10)$

$m =\frac{10-5}{2-(-3)}\\m=1$

Equation of straight line in slope intercept form is

$y-y_1=m(x-x_1)\\y-5=(x+3)$

$y=x+8$

Work out the perimeter of this semicircle with radius 3cm. Give your answer in terms of π

kondaur [170]

Step-by-step explanation:

<u>Given </u><u>:</u><u>-</u><u> </u>

A semicircle is given with radius of 3cm .

And we need to find the perimeter of the semicircle . We know the perimeter as ,

$:\implies$ Perimeter = πr

$:\implies$ Perimeter = 3cm × π

$:\implies$ Perimeter = 3π cm .

Now there is the diameter of circle is 6cm . Hence totally the perimeter is ,

$:\implies$ Perimeter = 3π + 6 cm

We were supposed to give answers in terms of π .

<h3>Hence the perimeter is ( 3π + 6 ) cm</h3>
