Answer: C≈62.83ft

Step-by-step explanation:

simply take your radius and times it by 2 and you get 20. then times twenty by pi.

Approximate circumference of circle is 20\pi feet that is 62.8 feet.

<u>Solution :</u>

Need to determine approximate circumference of a circle with radius as 10 feet.

So given that radius of circle = 10 feet

Circumference of circle is product of constant 2\pi with radius of circle r.

=> Circumference of circle = 2\pi r

On substituting the value of radius, we get circumference

So circumference of a circle of radius 10 feet = 2\pi \times 10 = 20\pi

Taking \pi = 3.14, we get circumference = 20 x 3.14 = 62.8 feet  

Hence approximate circumference of circle is 20\pi feet that is 62.8 feet.

Answer:

Therefore,

AB=16.25\ units

The Measurement of AB is 16.25 units.

Step-by-step explanation:

In Right Angle Triangle ABC

m∠C=90°

AC = 10.01    .....(Adjacent Side to angle A)

m∠A=52°

cos 52 ≈ 0.616

To Find:

AB = ? (Hypotenuse)

Solution:

In Right Angle Triangle ABC, Cosine Identity,

\cos A= \dfrac{\textrm{side adjacent to angle A}}{Hypotenuse}\\

Substituting the values we get

\cos 52= \dfrac{AC}{AB}=\dfrac{10.01}{AB}

But cos 52 ≈ 0.616 ....Given

AB=\dfrac{10.01}{0.616}=16.25\ units

Therefore,

AB=16.25\ units

The Measurement of AB is 16.25 units.

20 POINTS Find the diameter?? Pls help I dont know what to do..
Akimi4 [234]

Answer:

Diameter = 19.33

Step-by-step explanation:

Imaging a radius line from O to the endpoints of the 7. call this line R.

Label the part of the vertical line from O to the 90 degree intersection y.

Now you have a right triangle.

Using the Pythagorean theorem:

R² = 7² + y²

also

y = R - 3

substitute for y:

R² = 49 + (R-3)²

R² = 49 + R² - 6R + 9

simplify:

0 = 58 - 6R

6R = 58

R = 9.6667

Diameter = 2(9.6667) = 19.33

Sinx(cscx-sinx)=cos^2x
Yuri [45]

\bf sin(x)[csc(x)-sin(x)]~~=~~cos^2(x) \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ sin(x)\left[\cfrac{1}{sin(x)}-\cfrac{sin(x)}{1} \right]\implies \underline{sin(x)}\left[\cfrac{1-sin^2(x)}{\underline{sin(x)}} \right] \\\\\\ 1-sin^2(x)\implies cos^2(x)


recall again, sin²(θ) + cos²(θ) = 1.
