Jude says that the volume of a square pyramid with base edges of 12 in and a height of 10 in is equal to the volume of a cylinde

Lapatulllka [165]

Answer:

No, not correct

Step-by-step explanation:

Square pyramid volume: (1/3) (base area)(height). In this case,

V = (1/3)*(12 in)^2*(10 in) = 480 in^3 = 480 in^3

Cylinder volume: (base area)*(height). In this case,

V = (3.14)*(6.77 in)^2*(10 in) = 452.12 in^3.

No, Jude is not correct; the 480 in^3 volume of the square pyramid is not the same as the 452.12 in^3 volume of the cylinder.

Which of the following is a like radical to RootIndex 3 StartRoot 6 x squared EndRoot? x (RootIndex 3 StartRoot 6 x EndRoot) 6 (

aliya0001 [1]

Answer:

4 (RootIndex 3 StartRoot 6 x squared EndRoot) = 4 $\sqrt[3]{6x^2}$

Step-by-step explanation:

<em>Added radical forms to the question for better visibility.</em>

Which of the following is a like radical to RootIndex 3 StartRoot 6 x squared EndRoot = $\sqrt[3]{6x^2}$ ?

x (RootIndex 3 StartRoot 6 x EndRoot) = x $\sqrt[3]{6x}$
6 (RootIndex 3 StartRoot x squared EndRoot) = 6 $\sqrt[3]{x^2}$
4 (RootIndex 3 StartRoot 6 x squared EndRoot) = 4 $\sqrt[3]{6x^2}$
x (RootIndex 3 StartRoot 6 EndRoot) = x $\sqrt[3]{6}$

<h3>Solution</h3>

<em>Like radicals are radicals that have the same root number and expression under the root.</em>

1) x $\sqrt[3]{6x}$ = $\sqrt[3]{6x^4}$

No, incorrect

2) 6 $\sqrt[3]{x^2}$ = $\sqrt[3]{6^3x}$

No, incorrect

3) 4 $\sqrt[3]{6x^2}$

Yes, correct

4) x $\sqrt[3]{6}$ = $\sqrt[3]{6x^3}$

No, incorrect

Compared with the given radical, we can see from the given choices only 3rd choice is like radical with $\sqrt[3]{6x^2}$
