A landing pad for a helicopter is in the shape of a circle with a radius of 7 meters. Which of the following is closest to the a
ANTONII [103]

Answer:

The approximate value of the area is 153.86\ m^{2}

Step-by-step explanation:

we know that

The area of the circle (landing pad) is equal to

A=\pi r^{2}

we have

r=7\ m

substitute

A=\pi (7)^{2}

A=49\pi\ m^{2} ----> exact value of the area

Find the approximate value

assume \pi=3.14

A=49(3.14)=153.86\ m^{2} ------> approximate value of the area

Seven less than the quotient of a number, x, and twelve is five times the number. Which answer represents this situation??
erica [24]

Answer:

Option b is correct.

Step-by-step explanation:

From the given condition : Seven less than the quotient of a number, x, and twelve is five times the number.

Here, the number is x

The quotient of a number x and twelve is expressed as ,  \frac{x}{12}

Seven less than the quotient of a number, x, and twelve is expressed as,  \frac{x}{12}-7

Five times the number mean, 5x

Therefore, we have an equation in the form of <em>x</em>  from the given condition as:

\frac{x}{12}-7=5x .
