Answer:

Given the statement: Crater Lake in Oregon in shaped like a circle with a diameter of about 5.5 miles.

Area of circle is given by:

A = \pi \frac{d^2}{4}

where

A represents the area of a circle

d represents the diameter of a circle.

then;

It is given that Surface of Crater lake is shaped like a circle.

Substitute the given values, we have;

Area of a circle = \pi \frac{(5.5)^2}{4}

= 3.14 \times \frac{30.25}{4} =3.14 \times 7.5625 = 23.74625 square miles

therefore, the area of a surface of a crater lake is, 23.74625 square miles.

Original  

l = v/r

first multiply each side by r to get it out of the denominator

rl = v

now divide by l to get r by itself

r = l/v

Step-by-step explanation:

Original  

l = v/r

What is the product?
Leya [2.2K]

Answer:

5/4k^2

Step-by-step explanation:

P=5\dfrac{k}{6}\times \dfrac{3}{2k^3}.

We will be using the following property of exponents:

\dfrac{a^x}{a^y}=a^{x-y}.

We have

P\\\\\\=5\dfrac{k}{6}\times\dfrac{3}{2k^3}\\\\\\=\dfrac{5}{6}\times\dfrac{3}{2}k^{1-3}\\\\\\=\dfrac{5}{4}k^{-2}=\dfrac{5}{4k^2}.

Thus, the required product is \dfrac{5}{4k^2}.
