Need please solving for x​

Mathematics
1 answer:
koban [17]3 years ago
6 0

Answer:

x = 15

Step-by-step explanation:

Corresponding sides of similar shapes are proportional to each other. Thus:

(10 + 2)/10 = (x + 3)/x

12/10 = (x + 3)/x

Cross multiply

12*x = (x + 3)*10

12x = 10x + 30

12x - 10x = 30

2x = 30

x = 30/2

x = 15

the radius of a circle is 10 using pi which equation expresses the ratio of the circumference of the circle to the circle's diam
grigory [225]

Answer:

pi

Step-by-step explanation:

The radius of the circle is 10 units

The circumference of a circle is given by the formula:

  C = 2 * pi * r

The diameter of a circle is twice the radius

d= 2r

We want the ratio of the circumference to the diameter

C/d  = (2*pi*r)/ 2r  

Canceling out the 2 and the r, we are left with pi

C/d = pi
