navik [9.2K]

Answer:

A = 31.8 cm2

Step-by-step explanation:

Yhe formula:

$A=\frac{\pi r^{2}(Central.Angle) }{360}$

$r=18/2=9cm$

central angle = (180-135)° = 45°

$A=\frac{\pi ((9)^{2}(45) }{360} = \frac{\pi (81)(45)}{360} = 10.125\pi cm^{2}$

$A=31.8cm^{2}$

Hope this helps

Solve the following equation for x. Round the answer to the nearest hundredth.

Serhud [2]

Hence, option D 4: x=-1.34 is correct

Further explanation:

In order to solve an equation in one varible we have to isolate the variable on one side of the equations

Given equation is:

$-1.2x=2(x+2.15)\\Simplifying\\-1.2x=2x+4.3\\Subtracting\ 2x\ from\ both\ sides\\-1.2x-2x=2x+4.3-2x\\-3.2x=4.3\\Dividing\ both\ sides\ by\ -3.2\\\frac{-3.2x}{-3.2}=\frac{4.3}{-3.2}\\x=-1.34375\\Rounding\ off\ to\ nearest\ 100th\\x=-1.34$

Hence, option D: x=-1.34 is correct
