A patio in the shape of a semicircle has a diameter of 21 ft. What is the approximate area of the patio, rounded to the nearest square foot? Use 3.14 to approximate pi star times pi.

Answers

Answer 1

Answer: The formula of the area of a semi circle is half the area of the circle

$( \pi r^2)/(2)$

Diameter = 21 ft
Radius = $(d)/(2)$ = $(21)/(2)$ = 10.5 ft

Area = $( \pi (10.5)^2)/(2)$
= $(110.25 \pi )/(2)$
= $(110.25 * 3.14)/(2)$ (3.14 as $\pi$ )
= $(346.185)/(2)$
=173.0925 ft² ≈ 173.1 ft² ≈ 173 ft²
To the nearest square foot : 173 ft²

Through: (3,5), slope = 5/3

Answers

the formula is : y = mx + b so m is the slope and b is the y-intercept and now you have : 5 = 5/3(3) + b so you need b so you can say :
5 = 5/3(3) + b ⇒ 5 = 5 + b ⇒ 5 - 5 = b so b =0 so in this question we dont have any y-intercept so the answer is : y = 5/3x
but an other formula is : ( y - 5 ) = 5/3 ( x - 3 )
but the standard form is gonna be : y - 5/3x = 0 or 3y - 5x = 0 :))

What is the greatest common factor of the terms of 3y2 – 21y + 36?

Answers

Answer:3

Step-by-step explanation:

Final answer:

The greatest common factor of the terms of the polynomial 3y2 – 21y + 36 is 3. This is because 3 is the highest number that can divide each term of the polynomial evenly and only the first two terms have 'y', so 'y' cannot be considered as a common factor for all terms.

Explanation:

The greatest common factor (GCF) of the terms of a polynomial is the highest number or variable that divides each term of the polynomial evenly. In this case, to find the GCF of the terms of the mathematical expression 3y2 – 21y + 36, we need to look at each term separately.

For the terms 3y2, -21y, and +36, the GCF in numerical terms is 3. However, since only the first two terms have y as a variable, y is not a common factor for all terms. Hence, the greatest common factor of the terms of the polynomial 3y2 – 21y + 36 is 3.
