First, consider the formula for area of a circle:

Area of a circle= π r²

Secondly, because the diameter is double the radius, and we have been given the diameter, we can find the radius!

d/2=r
(240mm) / 2= r
120mm = r

Finally, now that we know the radius, we can find the area!

Area = π r²
= π (120)²
= π 14400mm² OR 45238.93 mm²

Hope this helps!

Write the number below in scientific notation, incorporating what you know about significant digits. 67,890,000

SVETLANKA909090 [29]

The answer would be: 67.89 x 10^6

The rules of significant numbers used:

- any non-zero digit is significant
- zeroes that are in the right side of the non-zero whole number would not be significant

Thus, only the significant numbers left in the equation:

67.89 x 10^6

At a certain electronics company, the daily output Q is related to the number of people A on the assembly line by Q=600+√(A+41).

Ber [7]

Answer:

$A=400\ people$

Step-by-step explanation:

we have

$Q=600+\sqrt{A+41}$

where

Q -----> is the daily output

A -----> is the number of people

For Q=621

Find the value of A

substitute and solve for A

$621=600+\sqrt{A+41}$

Subtract 600 both sides

$621-600=\sqrt{A+41}$

$21=\sqrt{A+41}$

squared both sides

$21^{2} ={A+41}$

$441={A+41}$

Subtract 41 both sides

$441-41=A$

Rewrite

$A=400\ people$

The function A = 15x - x2, where x is the width in yards, gives the area A of a llama pen in square yards. Make a table using 1/

Mnenie [13.5K]

Answer:

The width which gives the greatest area is 7.5 yd

Step-by-step explanation:

This is an application of differential calculus. Given the area as a function of the width, we simply need to differentiate the function with respect to x and equate to zero which yields; 15-2x=0 since the slope of the graph is zero at the turning points. Solving for x yields, x=7.5 which indeed maximizes the area of the pen
