The answer to you’re question is 60
Yakvenalex [24]3 years ago
6 0

Answer:

60

Step-by-step explanation:

Because the diameter of this circle is 20 and the formula for the circumference (perimeter) of a circle is pi * the diameter, or πd, which, if π is 3, can be computed as 60.

A takeaway from this problem is that you should memorize basic equations like the circumference/area of a circle.

RS = 3x - 16, ST = 4x - 8, RT = 60
lesya692 [45]

Answer:

RS = 20

ST = 40

Step-by-step explanation:

R____S____T

RS + ST = RT

3x - 16 + 4x - 8 = 60

3x + 4x - 16 - 8 = 60

7x - 24 = 60

    +24    +24

--------------------------------

7x = 84

/7     /7

---------------------------------

x = 12

Let's use what we got for x to find the length of ST and RS

ST = 4x - 8

= 4(12) - 8

= 48 - 8

ST = 40

RS = 3x - 16

= 3(12) - 16

= 36 - 16

RS = 20

so, RS = 20, ST = 40, and RT = 60

Find the value of x. Round to the<br> nearest tenth.<br> 15.6 cm<br> 8.8 cm<br> x = [ ? ]cm
kenny6666 [7]

Answer:

x = 4.1 cm

Step-by-step explanation:

To find x, apply pythagorean theorem, which is given as:

c² = b² + a²

Where,

c = 8.8 cm

b = ½(15.6) = 7.8 cm

a = x

Plug in the values

8.8² = 7.8² + x²

77.44 = 60.84 + x²

Subtract both sides by 60.84

77.44 - 60.84 = x²

16.6 = x²

Take the square root of both sides

√16.6 = x

x = 4.07430976

x = 4.1 cm (nearest tenth)
