In circle C, r = 32 units.<br> What is the area of circle C?
Gnoma [55]

Answer:

A = 1024π units², A ≈ 3216.99 units²

Step-by-step explanation:

The equation of the area of a circle is A = πr², where A = area and r = radius.

Given that, we can plug in r as 32 units: <em>A = π(32 un.)²</em>

Simplifying that gives us A = 1024π units², or A ≈ 3216.99 units²

Find the x intercept of the line 2x-3y=-19
Tju [1.3M]

Answer:

See below.

Step-by-step explanation:

Recall that the x-intercept is basically: (x,0).

In other words, we just need to substitute y with 0 in order to find the x-intercept.

Thus, we will have:

2x-3(0)=-19

2x=-19

x=-19/2

Solve the simultaneous equations<br> -x + 4y = 12<br> x + y = - 7
blondinia [14]

Answer:

y = 1, x = - 8

or

(-8, 1)

Step-by-step explanation:

-x + 4y = 12

x + y = -7

add the equations together

0x + 5y = 5

5y = 5

y = 1

substitute y for 1 in one of the original equations to find x

x + y = -7

x + 1 = -7

x + 1 - 1 = - 7 - 1

x = - 7 - 1

x = -8
