To the nearest hundredth, what is the area of a circle with a radius of 5 units?

Answers

Answer 1

Answer:

Answer: 78. 571 unit²

Step-by-step explanation:

To find the area of a circle, we simple use the formular;

area of a circle = Πr²

The value of π = 22/7

r= radius of the circle = 5

area of a circle = Πr²

= 22/7 × 5 ×5

=550 / 7

= 78. 57143

=78. 571 unit² to the nearest hundredth

Therefore area of the circle with radius 5cm is 78. 571 unit²

Ok, so I am changing this answer to the correct one based on what you said

Area (Square) = length times width

1yard^2⇒3feet^2⇒9^2

Then take 9 and divide 180 sq feet from it

180 ÷ 9 = 20 sq yards

Then multiply 20 by $15

20×$15=$300

Answer:

$300

180 square feet

So

3 feet = 1 yard
9 square feet = 1 square yard

180/9 = 20 square yards

20 x 15 = $300

which is your final answer (:

Step-by-step explanation:

Volume=4/3 πr³=4/3 π(6)³=288π m³

Answer:

Step-by-step explanation:

volume of sphere=4/3 πr^3

V=4/3×22/7×12×12×12

V=16×22×12×12/7

V=50688/7

V=7241.14286m^3

Which function is equivalent to y=x2-10x+9? A: Y=(x+5)^2+16
B: Y=(x-5)^2-16
C: Y=(x-5)^2+16
D: Y=(x+5)^2-16

Answers

Answer:

Step-by-step explanation:

Given

y = x² - 10x + 9

Using the method of completing the square

add/subtract (half the coefficient of the x- term)² to x² - 10x

y = x² + 2(- 5)x + (- 5)² - (- 5)² + 9

= (x - 5)² - 25 + 9

= (x - 5)² - 16 → B

Figure out the equation for each of the multiple choice.

Then you will get the answer .

For example:

a. (x+5)(x+5) +16

= x^2 + 5x+5x+25+16

= x^2+10x+41
