A tree trunk has a height of 30 feet and a radius of 2.5 what is the volume of the tree trunk

Mathematics
1 answer:
Fantom [35]3 years ago
7 0

Answer:

L.) 589 ft^{3}

Step-by-step explanation:

We can automatically asume that a Tree trunk is a cylinder. so the formula to find the volume of a cylinder is

V = \pi r^{2}h

So we have to substitue the values.

3.14 x (2.5 squared) x 30 = V

rewrite

<u>3.14 x 6.25</u> x 30 = V

19.625 x 30 = 588.75

Your exact volume is 588.75 ft^{3} But we can round it. so therfore your answer is L.) 589 ft^{3}

Hope this helped! Please mark a brainliest! Thanks!

Which algebraic expression is equivalent to the expression below? 6x+15y A. 3(2x - 5y) B. 3(5x - 2y) C. 3(2x + 5y) D. 3(5x + 2y)
Marina CMI [18]

Answer:

C. 3(2x + 5y) is the algebraic expression equivalent to the expression

Step-by-step explanation:

From the question, the given expression is 6x + 15y.

Factorizing this expression gives 3(2x + 5y). Hence, the algebraic expression equivalent to the expression 6x + 15y is 3(2x + 5y). (Option C).

Checking the remaining options

A. 3(2x - 5y)

Expanding this gives 6x - 15y. It is not equivalent to the given expression

B. 3(5x - 2y)

Expanding this gives 15x - 6y. It is not equivalent to the given expression

D. 3(5x + 2y)

Expanding this gives 15x + 3y. It is not equivalent to the given expression.

Hence, C. 3(2x + 5y) is the algebraic expression equivalent to the expression.
