Answer:

7pi or ≈21.98 cm²

Step-by-step explanation:

The area of the shaded and non shaded in the circle is pir^2 so pi3^2 so 9pi

the area of the 2 smaller circles is pi1^2*2 so 2pi

9pi-2pi=

7pi cm² =

7pi≈21.98 cm² (with pi as 3.14)

Step-by-step explanation:

Area of the large circle =πR²

=3.14×(3)²=3.14×9=28.26cm²

Area of one small circle= πr²= 3.14×1= 3.14cm²

Area of two small circles = 2×3.14 cm²= 6.28cm²

Area of the shaded region= (28.26-6.28)cm²

= 21.98 cm²

The equations could you use to find the price of one tire patch is 4x + 1.9 = 22.2.

The price of one patch is $5.075.

Given

To prepare for his mountain biking trip, Rhyan bought four tire patches.

Rhyan paid using a gift card that had $22. 20 on it.

After the sale, Rhyan’s gift card had $1. 90 remaining.

<h3>What is the equation?</h3>

An equation says that two things are equal.

Let, the price of one tire patch be x.

The equations could you use to find the price of one tire patch is;

\rm = \text{Total number of patches} \times Price \ of \ one \ patch + Remaining \ gift card= Total \ paid \ amount\\\\4x + 1.9 = 22.2\\\\4x=22.2-1.9\\\\4x=20.3\\\\x=\dfrac{20.3}{4}\\\\x=5.075

Hence, the price of one patch is $5.075.

the legs of a right triangle have lengths of 28 meters and 21 meters. the hypotenuse has a length of 5x meters. what is the valu
Hitman42 [59]
We have a right triangle with
a = one leg = 28
b = other leg = 21
c = hypotenuse = 5x

use the pythagorean theorem (a^2+b^2 = c^2) and solve for x

a^2+b^2 = c^2
28^2+21^2 = (5x)^2
784+441 = 25x^2
1225 = 25x^2
25x^2 = 1225
(25x^2)/25 = 1225/25
x^2 = 49
sqrt(x^2) = sqrt(49)
|x| = 7
x = 7 or x = -7

Since the hypotenuse has length 5x meters, this means
5x = 5*7 = 35
or
5x = 5(-7) = -35

Toss out the negative length as it makes no sense. 

The only value of x is x = 7

Therefore the final answer is x = 7
