Answer:

28.26 square inches

Step-by-step explanation:

Formula for area of a circle:

$A=\pi r^2$

Radius is 3.

$A= \pi (3)^2\\A=\pi 9$

Use 3.14 for pi:

$A = 3.14 * 9 = 28.26\\A=28.26$

The area should be 28.26 square inches.

Answer:

sin s = 36 / 42 = 18 / 21 = 6/ 7

sin R = 14 / 42 = 7 / 21 = 1 / 3

cos s = 14 / 42 = 1 / 3

cos R = 36 / 42 = 6 / 7

Help please my moms going to kill me if I don’t get this right

Answer:

$x=-\frac{41}{6}$

Step-by-step explanation:

Pay attention to the two tick marks. This indicates that those sides are congruent to each other and so will the angles on the bottom and top. Therefore, we can set up the equation $137+2(-3x+1)=180$ and solve for x:

$137+2(-3x+1)=180$

$137+(-6x+2)=180$

$137-6x+2=180$

$139-6x=180$

$-6x=41$

$x=-\frac{41}{6}$

Yara has 2 rectangular gardens in her backyard. The smaller garden is 1/2 foot long and 2/3

dimulka [17.4K]

Dimension of smaller garden :

l = 1/2 ft.

b = 2/3 ft.

Dimension of bigger garden :

L = 4 ft.

Let , breadth be x ft.

We know , area is given by :

Area = L×B.

Area of small garden = $\dfrac{1}{2}\times\dfrac{2}{3}=\dfrac{1}{3}\ ft^2$

Area of big garden $=4\times x=4x\ ft^2$

Hence, this is the required solution.

Answer:

$\huge\boxed{width=12cm}$

Step-by-step explanation:

$l-length\\w-width\\P-perimeter$

The formula of perimeter of the rectangle:

$P=2l+2w=2(l+w)$

Substitute:

$l=6w\\\\P=168cm$

$168=2(6w+w)\\168=2(7w)\\168=14w\qquad|\text{divide both sides by 14}\\\\\dfrac{168}{14}=\dfrac{14w}{14}\\\\12=w\Rightarrow w=12(cm)$
