The diameter of a circle is 28 millimeters. What is the circle's area<br><br> Use 3.14 for ​.
yulyashka [42]

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>

Simplify 5 to the negative 4th power over 5 to the 3rd. Group of answer choices 57 5−1 1 over 5 1 over 5 to the 7th power
STatiana [176]
When you divide exponents, you have to subtract them. So -4-3= -7 as the exponent

When you have a negative exponent, then you have to flip the fraction (all whole numbers are over 1 so flip the 1 to the top and the 5^7 on the bottom)
