Answer:

615.44 mm²

Step-by-step explanation:

Before finding the area of the circle, first, let us find the radius of the circle.

Given that,

diameter ⇒ 28 mm

Therefore,

<h3>d = 2r</h3>

28 = 2r

Divide both sides by 2.

14mm = radius

<u>                                             </u>

And now, let us find the area.

The formula to find the area of the circle is :

<h3>Area = π r²</h3>

Let us solve now.

Area = π r²

        = 3.14 × 14 × 14

        = 43.96 × 14

        =<u> 615.44 mm²</u>

Solve for a.<br> 4/a+4 =-1/a+9
Bad White [126]

Answer:

a = -8

Step-by-step explanation:

you can solve this proportion by cross-multiplying:

4(a + 9) = -1(a + 4)

now distribute to eliminate parentheses

4a + 36 = -1a - 4

5a + 36 = -4

5a = -40

a = -8

The distance between itahari and Damak is
Ludmilka [50]

Answer:

8 km by motorbike.

Step-by-step explanation:

The distance between itahari and Damak is  42 km.

Mr. Dhamala travelled 18.325 km by a  bus / 15.675 km by a taxi and the remaining distance by a motorbike.

Let he covered x distance by motorbike. So,

Remaining distance = Total distance -(distance covered by bus + distance by taxi)

= 42 -(18.325 +15.675 )

= 42-34

= 8 km

So, he travelled 8 km by motorbike.

Solve the equation <br> 5(x+4)+52= -4x
Maru [420]

Answer:

x = -8

Step-by-step explanation:

Given: 5(x+4)+52=-4x

Distributive Property: 5x+20+52=-4x

Combine like terms: 5x+72=-4x

Subtract 5x on both sides: 72=-9x

Divide both sides by -9: -8=x

Flip the equation around: x=-8

Therefore, x=-8

Rewrite the exponential expression 25^3/2as a radical expression-<br> plss helpp
Agata [3.3K]

Answer:

\huge\boxed{\sqrt{25^{3}}}

Step-by-step explanation:

When we have a number to a fraction power, we need to note that

  • It's the same as taking the denominator root of the base to the numerator power

Basically, for example, 5^{\frac{1}{2}} is the same as \sqrt{5} since the numerator is 1 (5^1 = 5) and the denominator is 2 (\sqrt{5}).

Applying this same logic to 25^{\frac{3}{2}} -

25^{3}

\sqrt{25^3}

Hope this helped!
