Answer

-5/3, -1, 0.7, √2, √5

Explanation

√5 = 2.236

-1 ⇒ this is less than 1.

-5/3 = -1.666667 this is less than 1. -5/3 < -1

0.7 > -1

√2 = 1.414 ⇒ √5 > √2

Arranging them from the least to the greatest;

-5/3, -1, 0.7, √2, √5

Question 7

serg [7]

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

Given - a cone with volume 769?3 ft³ , having a height of 15 ft

To calculate - radius of the cone

We know that ,

$\bold{Volume \: of \: cone = \frac{1}{3}\pi \: r {}^{2} h }\\$

substituting the values in the formula stated above ,

$\bold{769.3 = \frac{1}{3} \times 3.14 \times r {}^{2} \times 15} \\ \\\bold{\implies r {}^{2} = \frac{769.3 \times 3}{3.14 \times 15} } \\ \\\bold{\implies r {}^{2} = \cancel\frac{2307.9}{47.1}} \\ \\\bold{ \implies \: r {}^{2} = 49} \\ \\ \bold{\implies \: r = 7 \: ft}$
