The diameter of the cell model according to the taks content is; 14in.

<h3>Diameter of the cell model</h3>

Volume of paint = 615.44 square inches

π = 3.14

Volume of a sphere = 4πr²

615.44 = 4 × 3.14 × r²

615.44 = 12.56/r²

r² = 615.44 ÷ 12.56

r² = 49

r = 7

Hence, the diameter of the cell is; 2 × r = 2 × 7 = 14in.

Answer:

1.  62.95

2.  63.37

3.  63.7

Step-by-step explanation:

List the numbers by lining up the decimals and filling in zeros in the empty spaces to make all the numbers have the same number of digits,  then compare whole numbers first then the decimals.  There are two 63's so then you look at the decimal side one is .37 and one is .70 (add the zero so all numbers have the same number of digits)

63.37

62.95

63.70 (added the zero)

Need help asap show your work
Monica [59]

To find the volume we use an equation:

volume = length x width x height

Since this shape is a cube, you only need to know one side to find the volume since all of the sides are equal.

So all you need to find the volume is to multiply 4(1/2) which I am going to simplify to 4.5, is plug it into the equation.

volume = 4.5 x 4.5 x 4.5

Which will get you an answer of 91.125 inches cubed

91.125in^{3}

Hope this helps :)

A triangle has sides with lengths of 18 centimeters, 68 centimeters and 74 centimeters. Is it a right triangle?
Hoochie [10]
18^2 + 68^2 =

= 324 + 4,624

= 4,948

74^2 = 5,476

4,848 is not equal to 5,476.

Since the sum of the squares of the lengths of the two shorter sides is not equal to the square of the length of the longest side, the triangle is not a right triangle.

Can u tell me if my answers are correct here?
MariettaO [177]
By the process of elimination, it is already not the last 2, so it is 50/50 chance to get it correct, but if you know how to add, you can figure out that 1 million per year in 5 years means that it is 12 million + 5 million, which is equal to 17 million and not 14,500,000. This brings it down only to 500,000$ salary increase per year
