Find the radius of the circle below. Round your answer to the nearest tenth.

Butoxors [25]

Answer:

5.8 cm

Step-by-step explanation:

Area of the shaded sector of the circle = 31.2 cm²

Angle (θ) of the minor sector = 360 - 256 = 104°

Are of sector of a circle is given as, θ/360*πr²

Therefore:

$\frac{104}{360}*3.142*r^2 = 31.2$

$0.29*3.142*r^2 = 31.2$

$0.91*r^2 = 31.2$

Divide both sides by 0.91

$\frac{0.91*r^2}{0.91} = \frac{31.2}{0.91}$

$r^2 = \frac{31.2}{0.91}$

$r^2 = 34.286$

$r = \sqrt{34.286}$

$r = 5.8$ (nearest tenth)

Eighth grade ) T.5 Pythagorean theorem: word problems 87U

Komok [63]

Answer:

The tree is 12 feet tall

Step-by-step explanation:

Let a represent the length of where the bird was sitting to the oak tree

let b represent the height of the tree

let c represent the length at which the bird flew

by pythagoras theorem

c²=a²+b²

b²=c²-a²

$b = \sqrt{ {c}^{2} - {a}^{2} }$

subtitute in the values

$b = \sqrt{ {15}^{2} - {9}^{2} }$

$b = \sqrt{225 - 81}$

$b = \sqrt{144}$

$b = 12$
