Answer:
They would need approximately 20 gallons of paint for the water tower, so yes, 25 gallons would be enough.
Step-by-step explanation:
In order to find out if there is enough paint for the surface area of the sphere, you need to first find the radius of the object so you can determine the measure of the entire surface area. Since they give us the volume, we can use that to solve for the radius using the volume formula: V =
πr³ or 66840.28 =
πr³. Using inverse operations, you can first multiply both sides of the equation by the reciprocal of 4/3 or 3/4, then divide by π, this gives you 15,965 = r³. In order to find 'r', take the cube root of both sides: ∛15965 = ∛r³ or r ≈ 25.
Now that you know radius = 25, you can use the formula for surface area: SA = 4πr² or 4π(25)² ≈ 7850 ft². Since one gallon of paint covers 400 square feet, we can take our total and divide by 400 to find the number of gallons: 7850 ÷ 400 ≈ 19.6. In total, we would need 19.6 gallons of paint for the water tower, so if there are 25 gallons available, there is enough.
Step-by-step explanation:
It's simple here's The steps:
*Step 1
-Take your ruler and a pencil and construct a segment of any length on a piece of paper
-Then, you will try to set your compass opening to match the length of segment AB
-Take your compass. Make your sure that the pencil is included in it.
-Put the needle of the compass at endpoint A and adjust your compass so that the tip of your pencil touches endpoint B
*Step 2
-Put the needle of your compass at A and draw an arc
-Put the needle of your compass at B and draw an arc
-The two arcs should meet
*Step 3
-Draw the segments from the two endpoints to the point where the two arcs intersect
Answer:
7/12
Step-by-step explanation:
1/4 +1/3
We need to get a common denominator of 12
1/4*3/3 = 3/12
1/3 *4/4 = 4/12
3/12+4/12 = 7/12
Answer:
bro what's the question and there is no doc
Step-by-step explanation:
The points: (0,4), (1,8),(2,10) is NOT a linear function as it doesnt pass the verticle line test. Linear function should always be in a straight line. Examples of linear functions: 4x + 3y = 6. Examples of nonlinear functions: y = 8x^2 + 10.
