Given a circle with measures of (C, d, and r) and a circle with measures of (C', d', and r'), what is r if C C' = 5 and d' = 20?

PtichkaEL [24]

Answer:

The value of radius r is 50

Step-by-step explanation:

Given as :

The measure of two circles as

Circumference = c Circumference = c'

Diameter = d Diameter = d'

Radius = r Radius = r'

And

$\frac{c}{c'}$ = 5

d' = 20

∴ circumference of circle = $2\times \Pi \times r$ = $\Pi \times d$

Or, $\frac{c}{c'}$ = $\frac{2\pi r }{\pi d'}$

Or, 5 = $\frac{2r}{d'}$

Or, 5 = $\frac{2r}{20}$

∴ 2 × r = 5 × 20

I.e r = 50

Hence The value of radius r is 50 Answer

Answer:

13.31803792

Step-by-step explanation:

Law of Cosines

a= 8

b= 18

c= ?

$c^2=a^2b^2-2ab*cos(c)$

$c^2=8^2-18^2-2*8*18*cos(43)$

c = 64 + 324 - 2 * 8 * 18 * cos(43)

cos(43) = 0.7313537016

Order of Operations

64 + 324 - 2 * 8 * 18 * 0.7313537016 = 177.3701339

Square Root the answer

$\sqrt{177.3701339}$ = 13.31803792
