The area of a circle is 28.26 square kilometers. What is the circles diameter

irinina [24]

Answer:

6km

Step-by-step explanation:

Area of circle = πr²

Where r = radius, π= 3.14, A = 28.26km²

A = 3.14 x r²

3.14 r2 = 28.26

Divide both sides by 3.14

r²= 28.26/3.14

r² = 9

Square root both sides

r= √9

r= 3

Radius = 3km

Note : Diameter = 2 x radius

Diameter = 3 x 2

Diameter = 6km

Find the exact volume of a cone 6yd height 5yd base

Verdich [7]

Answer:

The exact volume of a cone is 10 yd³.

Step-by-step explanation:

Given:

Height of cone (h) is 6 yd and base (b) is 5 yd.

Now, to get the volume we need to find the radius.

So, to find radius we put the formula of base:

Let the radius be $r$

Base= $\pi r^2$

$b=\pi\times r^{2}$

$5=\pi\times r^{2}$

Dividing both sides by π and using square root on both the sides:

$5\div \pi=(\pi \times r^{2}) \div \pi$

$\frac{5}{\pi}=r^{2}$

$\frac{5}{\pi}=r^{2}$

$r^{2}=\frac{5}{\pi}-----1$

Now, putting the formula for getting the volume (v) of cone:

Volume = $\pi r^2\frac{h}{3}$

$v=\pi\times r^{2}\times \frac{6}{3}$

$v=\pi\times r^{2}\times 2$

Substituting the value of $r^2$ from equation (1), we get:

$v=\pi\times \frac{5}{\pi}\times 2$

$v=10$ yd³

Volume of cone is 10 yd³

Therefore, the exact volume of a cone is 10 yd³.
