AreA of a circle pls help

Oksi-84 [34.3K]

Answer:

28.26 $in^{2}$

Step-by-step explanation:

Given,

Radius of the circle = 3in.

Area = ?

They have told us to use 3.14 for $\pi$

Area formula = $\pi r^{2}$

=> 3.14 * 3 * 3

=> 3.14 * 9

=> 28.26 $in^{2}$

Therefore the area of the circle is 28.26 $in^{2}$

Hope it helps :)

What is the value of x? geometry

Tpy6a [65]

Answer:

x = 35°

Step-by-step explanation:

A straight line = 180

180 - 95 = 85

The triangle has 180 degrees.

60 + 85 = 145

180 - 145 = 35

x = 35°

X^{2}-7x-25=0 to the nearest tenth

shepuryov [24]

Answer:

x = 9.6

x = - 2.6

Step-by-step explanation:

$x=\frac{-b±\sqrt{b^{2}-4ac } }{2a}$

Ignore the before the ± it wouldn't let me type it correctly.

x² - 7x - 25 = 0

a = 1

b = - 7

c = - 25

$x=\frac{-(-7)±\sqrt{-7^{2}-4((1)(-25)) } }{2(1)}$

$x=\frac{7±\sqrt{49-4((1)(-25)) } }{2(1)}$

$x=\frac{7±\sqrt{49+100 } }{2(1)}$

$x=\frac{7±\sqrt{149 } }{2}$

$x=\frac{7±12.2}{2}$

Two separate equations

$x=\frac{7+12.2}{2}$

$x=\frac{7-12.2}{2}$

$x=\frac{7+12.2}{2}$

$x=\frac{19.2}{2}$

x = 9.6

$x=\frac{7-12.2}{2}$

$x=\frac{-5.2}{2}$

x = - 2.6

X/4 -3 = 1/3 + 2x solve for x

ivann1987 [24]

Answer:

Step-by-step explanation:

$\frac{x}{4}$ - 3 = $\frac{1}{3}$ + 2x ...... <em>(1)</em>

(1) × 12 :

3x - 36 = 4 + 24x

21x = - 40

x = - $\frac{40}{21}$ = $-1\frac{19}{21}$
