Answer:

8 units

Step-by-step explanation:

The circumference of a circle is given by

C = 2*pi*r

50.24 = 2 * 3.14 *r

50.24 = 6.28 r

Divide each side by 6.28

50.24/6.28 = 6.28r/6.28

8 =r

Given that rectangle MNOP ~ rectangle STUV, what is the length of ¯¯¯¯¯¯ T U ?Rectangle M N O P is shown with segment N O labele

Sergeu [11.5K]

Answer:

$TU = 15$

Step-by-step explanation:

Given

$\square MNOP \simeq\ \square STUV$

$NO = 10$

$OP = 4$

$TU = x$

$UV = 6$

Required

Determine the length of TU (i.e. x)

Because both shapes are similar, then the following equivalent ratios exist:

$NO : OP = TU : UV$

Substitute values for NO, OP, TU and UV

$10 : 4 = x : 6$

Represent as fraction

$\frac{10 }{ 4 } = \frac{x }{ 6}$

Multiply both sides by 6

$6 * \frac{10 }{ 4 } = \frac{x }{ 6} * 6$

$6 * \frac{10 }{ 4 } = x$

$x = 6 * \frac{10 }{ 4 }$

$x = \frac{60 }{ 4 }$

$x = 15$

Hence:

$TU = 15$
