Answer:

$lets \: \: \: find \: \: the \: \: radius \\ = 2\pi \: r \\ = 2\pi \: r = 84 \\ = \frac{2\pi \: r}{2\pi } = \frac{84}{2\pi} \\ = r = 13.37mm$

$lets \: \: \: find \: \: the \: \: \: area \\ = \pi {r}^{2} \\ = \pi \times {13.37}^{2} \\ = 561.55 {mm}^{2}$

$lets \: \: \: find \: \: \: the \: \: diameter \\ = d = 2r \\ = d = 2 \times 13.37 \\ = d = 26.74mm$

A spinner is divided into 10 equal sections numbered 1 through 10. If the arrow is spun once, what is the probability it will la

yarga [219]

The correct answer is A) 2/5

That is because the probability of it is equal to the number of numbers larger than 6 divided by 10, which is 4/10, or 2/5 when reduced.

A sector with a central angle measure of \purpleD{175\degree}175°start color #7854ab, 175, degree, end color #7854ab has a radiu

Alisiya [41]

Answer: $219.94\ cm^2$

Step-by-step explanation:

Given

The central angle of a sector measures $175^{\circ}$

The radius of the circle is $r=12\ cm$

The area of the sector is given by

$\Rightarrow A=\dfrac{\theta }{360^{\circ}}\pi r^2$

Insert the values

$\Rightarrow A=\dfrac{175^{\circ}}{360^{\circ}}\cdot \pi \times 12^2\\\\\Rightarrow A=219.94\ cm^2$

Quadrilateral ABCD is inscribed in this circle.

miskamm [114]

The measure of angle A is 65°

Explanation:

Given that ABCD is a quadrilateral inscribed in a circle.

The measure of angle A is $\angle A=(2x+1)^{\circ}$

The measure of angle B is $\angle B=148^{\circ}$

The measure of angle D is $\angle D=x^{\circ}$

We need to determine the measure of angle A.

Since, we know that the angles B and D are opposite angles and the opposite angles of a quadrilateral add up to 180°

Thus, we have,

$\angle B+\angle D=180^{\circ}$

Substituting the values, we have,

$148^{\circ}+x=180^{\circ}$

$x=32^{\circ}$

Thus, the value of x is 32°

Substituting the value of x in the measure of angle A, we get,

$\angle A=(2x+1)^{\circ}$

$\angle A=(2(32)+1)^{\circ}$

$\angle A=(64+1)^{\circ}$

$\angle A=65^{\circ}$

Thus, the measure of angle A is 65°
