Find the arc length of the semicircle. Either enter an exact answer in terms of π or use 3.14 and enter your answer as a decimal

cricket20 [7]

Answer:

The arc length of the semicircle is $5 \pi\ units$ or $15.7\ units$

Step-by-step explanation:

The complete question in the attached figure

we know that

The circumference of a semicircle is given by the formula

$C=\frac{1}{2}\pi D$

where

D is the diameter of the semicircle

we have

$D=10\ units$

substitute

$C=\frac{1}{2}\pi (10)$

$C=5 \pi\ units$ ----> exact value

Assume

$\pi =3.14$

$C=5(3.14)=15.7\ units$ ----> approximate value

therefore

The arc length of the semicircle is $5 \pi\ units$ or $15.7\ units$

X^{2} -25=0 Please help meeee

-BARSIC- [3]

Answer:

$x=5,x=-5$

Step-by-step explanation:

$x^2-25=0$

Add 25 to both sides:

$x^2-25+25=0+25$

$x^2=25$

Square root both sides:

$x=\sqrt{25},\:x=-\sqrt{25}$ (Since a negative number multiplied by itself gives positive, there are two answers.)

$x=5,x=-5$
