Answer:

Area of training wheel is 285.74 square inches smaller than bicycle wheel.

Step-by-step explanation:

Given : A bicycle training wheel has a radius of 3 inches. The bicycle wheel has a radius of 10 inches.

To find : How much is the the area of the training wheel than the area of the regular wheel?

Solution :

→A bicycle training wheel has a radius of 3 inches.

Area of of the training wheel is $A=\pi r^2$

where r is the radius and r=3 inches (given), $\pi =3.14$

$A_1=\pi r^2$

$A_1=(3.14) (3)^2$

$A_1=3.14\times9$

$A_1=28.26 inches^2$

Area of the bicycle training is 28.26 square inches.

→ The bicycle wheel has a radius of 10 inches.

Area of of the bicycle wheel is $A=\pi r^2$

where r is the radius and r=10 inches (given), $\pi =3.14$

$A_2=\pi r^2$

$A_2=(3.14) (10)^2$

$A_2=3.14\times100$

$A_2=314 inches^2$

Area of the bicycle wheel is 314 square inches.

The area of the training wheel than the area of the regular wheel is

$Area=314-28.26=285.74$

Rounded to nearest hundredth the area is 285.74 square inches.

Therefore, Area of training wheel is 285.74 square inches smaller than bicycle wheel.

3t(t+2)-3t^2 for t=19

nekit [7.7K]

Good evening Gloria

3t(t+2)-3t² for t=19

Well the first thing we need to do is to replace 19 everywhere we see T

So let's do it together

3(19)(19+2)-3(19)²

57(21)-3(361)

1197-1083

= 114

I hope that's help and if you have questions please let me know :)

Please give my answer a Thanks and stars ↓

Express 9.21212121212... as a rational number, in the form pq

Mice21 [21]

$x=9.212121\ldots=9.\overline{21}$
$100x=921.212121\ldots=921.\overline{21}$
$99x=921.\overline{21}-9.\overline{21}=921-9=912$
$\implies x=\dfrac{912}{99}=\dfrac{304}{33}$
