The area of the circle is 132.7 square centimeters. What is the diameter

1 answer:

7 0

Equating the formula (d is the diameter)

$\pi$ d^2/4 = 132.7
d^2 = 132.7*4/ $\pi$
d = $\sqrt{169.044586}$
d = 13.0017147331
d= 13cm

Select an equation that passes through the point (5,7) and is perpendicular to the line x=4

alexandr1967 [171]

y = 7

x = 4 is a vertical line parallel to the y- axis passing through all points with an x- coordinate of 4

A line perpendicular to x = 4 will be a horizontal line parallel to the x- axis with equation y = c where c is the value of the y- coordinate the line passes through.

line passes through (5 , 7) with y- coordinate 7

The equation is therefore y = 7

Answer:

B. 18 cm.

Step-by-step explanation:

Because they are similar, we can say that segment AC corresponds to segment DF, and segment AB corresponds to segment ED. So, we can set up a proportion.

$\frac{16}{24} =\frac{12}{x}$
