work out the circumfrance of this cirlce take pi to be 3.142 and write down all the digits given by your calculator raduis 10cm

Simora [160]

Answer:

$C=68.4$

Step-by-step explanation:

$Circumference=2\pi r$

Pi = 3.142

r (radius) = 10 cm

$C=2(3.142)(10)$

$C=(6.84)(10)$

$C=68.4$

Therefore, circumference of a circle with 10 cm radius is <u>68.4.</u>

Find all the missing dimensions when a=9, b=13, c=64°

DerKrebs [107]

Answer:

Part 1) $c=12.14\ units$

Part 2) $m\angle A=41.78^o$

Part 3) $m\angle B=74.22^o$

Step-by-step explanation:

step 1

Find the measure of side c

Applying the law of cosines

$c^2=a^2+b^2-2(a)(b)cos(C)$

we have

$a=9\ units\\b=13\ units\\C=64^o$

substitute

$c^2=9^2+13^2-2(9)(13)cos(64^o)$

$c^2=81+169-234cos(64^o)$

$c^2=250-234cos(64^o)$

$c^2=147.4212$

$c=12.14\ units$

step 2

Find the measure of angle A

Applying the law of sines

$\frac{a}{sin(A)}=\frac{c}{sin(C)}$

substitute the given values

$\frac{9}{sin(A)}=\frac{12.14}{sin(64^o)}$

solve for sin(A)

$sin(A)=\frac{sin(64^o)}{12.14}(9)$

$sin(A)=0.6663$

$m\angle A=sin^{-1}(0.6663)=41.78^o$

step 3

Find the measure of angle B

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

so

$m\angle A+m\angle B+m\angle C=180^o$

substitute the given values

$41.78^o+m\angle B+64^o=180^o$

$m\angle B+105.78^o=180^o$

$m\angle B=180^o-105.78^o$

$m\angle B=74.22^o$

In the figure, x:y = 2:3 and y:z = 3:5. If x = 10, find the value of z. 15 20 25 30

Solnce55 [7]

x:y =x: y

10: y =2:3

2y=30

y=15

y:z=y:z

15:z=3:5

3z=75

z=25
