The diameter of a circle is 10 kilometers. What is the circle's radius?<br> d=10 km

alexandr402 [8]

Step-by-step explanation:

Let diameter of the circle be d and radius be r.

$\therefore \: r = \frac{d}{2} \\ \\ \therefore \: r = \frac{10}{2} \\ \\ \therefore \: r = 5 \: kilometers.$

Hence radius of the circle is 5 kilometers.

A triangular prism has a base that is 6 cm by 4 cm and a height of 8 cm. If all dimensions are tripled, what happens to the volu

lana [24]

Im assuming the base of the triangle is 4cm. The volume is $96cm^{3}$ .
If the dimensions are tripled, the base is 12, the height is 24, and the length is 18. The volume is $2592cm^{3}$ , which is 27 times bigger.
If you are increasing each side by a factor of x, you are multiplying the original by $x^{3}$

Evaluate 3^2018 + 3^2015 / 3^2017 + 3^2016

Harlamova29_29 [7]

The simplified value of the expression given as 3^2018 + 3^2015 / 3^2017 + 3^2016 is 7/3

<h3>How to evaluate the expression?</h3>

The expression is given as:

3^2018 + 3^2015 / 3^2017 + 3^2016

Factor out 3^2015 in the expression

So, we have

3^2015(3^3 + 1)/3^2015(3^2 + 3)

Cancel out the common factor

(3^3 + 1)/(3^2 + 3)

Evaluate the exponents

(27 + 1)/(9 + 3)

This gives

28/12

Simplify

7/3

Hence, the simplified value of the expression given as 3^2018 + 3^2015 / 3^2017 + 3^2016 is 7/3
