The area of the circle is 249 square feet. find the diameter

bulgar [2K]

Answer:

2 x $\sqrt{\frac{249}{\pi } }$ ft or 17.8055 ft

Step-by-step explanation:

Area= $\pi r^{2}$

249= $\pi r^{2}$

Solve for r.

r= $\sqrt{\frac{249}{\pi } }$

Multiply by 2 to get diameter.

The length of a diagonal of a quadrilateral shaped field Is 48 m And the length of perpendicular dropped on it from the remainin

olchik [2.2K]

Answer:

$1008\text{ m}^2$

Step by step explanation:

Please find the attachment.

We have been given that the length of a diagonal of a quadrilateral shaped field Is 48 m. The length of perpendicular dropped on it from the remaining apposite vertices are 16 m and 26 m.

We can see from our attachment that diagonal AC divides our quadrilateral field into two triangular fields and AC will be the base of both triangles.

To find the area of our given quadrilateral we will find the areas of both triangles and add the areas.

Let us find area of triangle ABC with base 48 m and height 26 m.

$\text{Area of triangle}=\frac{1}{2}(\text{ Base}\times\text{ Height})$

$\text{Area of triangle ABC}=\frac{1}{2}\times 48\times 26$

$\text{Area of triangle ABC}=24\times 26$

$\text{Area of triangle ABC}=624$

Therefore, the area of triangle ABC will be 624 square meters.

Now let us find area of triangle ADC with base 48 m and height 16 m.

$\text{Area of triangle ADC}=\frac{1}{2}\times 48\times 16$

$\text{Area of triangle ADC}=24\times 16$

$\text{Area of triangle ADC}=384$

Therefore, the area of triangle ADC will be 384 square meters.

Now let us add areas of triangles ABC and ADC to get the area of our quadrilateral ABCD.

$\text{Area of quadrilateral ABCD}=384+624$

$\text{Area of quadrilateral ABCD}=1008$

Therefore, the area of quadrilateral shaped field will be 1008 square meters.

Solve this equation for d. 32.6 = 17.3 – d

Vsevolod [243]

<span>Simplifying 32.6 = 17.3 + -1d Solving 32.6 = 17.3 + -1d Solving for variable 'd'. Move all terms containing d to the left, all other terms to the right. Add 'd' to each side of the equation. 32.6 + d = 17.3 + -1d + d Combine like terms: -1d + d = 0 32.6 + d = 17.3 + 0 32.6 + d = 17.3 Add '-32.6' to each side of the equation. 32.6 + -32.6 + d = 17.3 + -32.6 Combine like terms: 32.6 + -32.6 = 0.0 0.0 + d = 17.3 + -32.6 d = 17.3 + -32.6 Combine like terms: 17.3 + -32.6 = -15.3 d = -15.3 Simplifying d = -15.3</span>

Plz help answer fast

Tems11 [23]

Answer:

You see x is just the multiplied side of the opposite one, and you know 180 is half of 360 (full degrees). X=10 divided by 9 which is more than one, and the answer that belongs in the box is 10 divided by 9 is 180x10 and thats your answer :)
