Answer:

5/18

Step-by-step explanation:

note: 5/9 is the same as 10/18 (we get this by multiplying both numerator and denominator by 2)

hence

5/9-5/18

= 10/18 - 5/18

= (10-5) / 18

= 5/18

Simplify (5+1)^2-(12+3^2)/3

lakkis [162]

Answer:

Step-by-step explanation:

Simplify the expression $(5+1)^2-\dfrac{12+3^2}{3}$ step by step:

$(5+1)^2=6^2=6\cdot 6=36$

$\dfrac{12+3^2}{3}=\dfrac{12+3\cdot 3}{3}=\dfrac{12+9}{3}=\dfrac{21}{3}=7$

Now,

$(5+1)^2-\dfrac{12+3^2}{3}=36-7=29$

Find the area of the region shaded in green. Use 3.14 to approximate pi.

8090 [49]

Answer:

254 cm² (to 3 s.f.)

Step-by-step explanation:

Area of shaded region

= area of large circle -area of smaller circle

$\boxed{area \: of \: circle = \pi {r}^{2} }$

Radius of large circle= 15cm

Radius of smaller circle= 12cm

Area of shaded region

= π(15²) -π(12²)

= 225π -144π

= 81π

= 81(3.14)

= 254.34

= 254 cm² (3 s.f.)

I will give brainliest answer

Answer: A=351.68 cm²

Step-by-step explanation:

To find the area of the shaded region, we would subtract the area of the circle by the area of the inner circle.

Area of Circle

$A=\pi r^2$

$A=\pi (11)^2$

$A=121\pi$

Area of inner (white) circle

$A=\pi r^2$

$A=\pi (3)^2$

$A=9\pi$

Now that we have the area to the circle and inner circle, we would subtract to find the area of the shaded region.

$A=121\pi -9\pi$

$A=112\pi$

$A=351.68 cm^2$
