A semicircular flower bed has a diameter of 3 metres. What is the area of the flower bed?

Answers

The area of circle is

$A_{\text{circle}}=\pi r^2.$

Then the area of semicircular region is

$A_{\text{semicircular region}}=(1)/(2) \pi r^2.$

If r=3 m, you have

$A_{\text{semicircular region}}=(1)/(2) \pi \cdot 3^2=(9\pi)/(2)=4.5\pi \approx 14.13$ sq. m.

Answer: $A_{\text{semicircular region}}=4.5\pi \approx 14.13$ sq. m.

Answer:

Graphing Systems of Linear Inequalities

To graph a linear inequality in two variables (say, x and y ), first get y alone on one side. ...

If the inequality is strict ( < or > ), graph a dashed line. ...

Finally, pick one point that is not on either line ( (0,0) is usually the easiest) and decide whether these coordinates satisfy the inequality or not.

Hey there!

In order to convert a fraction to a decimal you have to DIVIDE the NUMERATOR (the TOP number) by the DENOMINATOR (the BOTTOM number).

The formula is:

a/b

= a ÷ b

= c

Whereas, “a” is your numerator, “b” is your denominator, & “c” is your decimal

Now that we have that information out the way we can answer your question.

4/5

= 4 ÷ 5

= 0.80

Therefore, your answer is: Option B. 0.8

Good luck on your assignment and enjoy your day!

A quadratic function and an exponential function are graphed below. Which graph most likely represents the exponential function?graph of function g of x is a curve which joins the ordered pair 0, 1 and 1, 2 and 3, 8 and 5, 32 and 6, 64. Graph of function f of x is a curve which joins the ordered pair 0, 1 and 1, 2 and 3, 10 and 5, 26 and 6, 37

f(x), because an increasing quadratic function will eventually exceed an increasing exponential function
g(x), because an increasing exponential function will eventually exceed an increasing quadratic function
f(x), because an increasing exponential function will always exceeds an increasing quadratic function until their graphs intersect
g(x), because an increasing quadratic function will always exceeds an increasing exponential function until their graphs intersect
