Steve has a steel barrel with a diameter of 4 feet that can be filled to a depth of 4.3 feet with oil. What is the volume of the barrel?Use = 3.14

A.
54.008 cubic feet

B.
51.6 cubic feet

C.
78.128 cubic feet

D.
17.708 cubic feet

Answers

Answer:

Option A. 54.008 cubic feet

Step-by-step explanation:

we know that

The volume of the barrel is equal to

$V=\pi r^(2)h$ ----> volume of the cylinder

we have

$r=4/2=2\ ft$ ----> the radius is half the diameter

$h=4.3\ ft$ ---> is the depth

$\pi =3.14$

substitute

$V=(3.14)(2)^(2)(4.3)$

$V=54.008\ ft^(3)$

Answers

The answer is 36 m.

This is really simple. To solve, multiply the length and the width and BAM! There's your answer. So for this problem, multiply 12 by 3 and don't forget to include the unit measurement.

12 * 3 = 36
Area = 36 m

Hope this helps! :)

Saul got 19 out of 25 on the test. Cindy got 79% on a same test which student got the higher mark?

Answers

19 divided by 25= .76 (.76x100= 76%)
Sal=76%
Cindy=79%
Cindy got higher grade

When you cross multiply ....19/25=x/100.....you get "x" equalls 76%. So Saul scored a 76% and Cindy scored a 79%. Now you tell me, who got the higher mark? (;

The area of a triangular field is 900msquare what is the base of the triangle if the height is 60m

Answers

Area formula of a triangle is:
A = $(1)/(2)$ bh
We know the are and the height, so substitute to find the base
900 m² = $(1)/(2)$ × b × 60 m
900 = 30b
Divide by 30 to isolate b
$(900)/(30) = (30b)/(30)$
30 and 30 cancels out
b = 30 m

Base of this triangle is 30 m

How do you make nine fourths a equliavent fraction

Answers

9/4 -->

See how many times 4 goes into 9. Then take the leftover and put it over the denominator.

So, 4 goes into 9 twice, to get 8.
With 1 leftover, you put it over the denominator, 4.

So, you get: 2 and 1/4

In other words, you would be putting your final answer into a mixed fraction.

You would divide 9 by 4

4 goes into 9 twice..., 4x2=8.

9-8=1

Use the remainder and divisor to write your fraction part and 2 as your whole number.

Answer: 2 1/4

Answer= 4
