Which is the closest approximation to the area of the circle? Use 3.14 or 22/7 to approximate π.

Answers

Answer 1

Answer: area=pi times r^2

radius=18mm
pemdas
exponents first
18^2=324
pi aprox=3.14
324 times 3.14=1017.36 mm^2 or square mm

Answer 2

Answer: For a circle, A= $\pi$ $r^(2)$
For this circle the radius is 18mm so when we plug it in we get A= $\pi (18)^(2)$
$18^(2) = 324$ so now we have A=324 $\pi$
Using 3.14 as $\pi$ We now have A=(3.14)(324) which is equal to 1017.36
So we know that A=1017.36 $mm^(2)$

Suppose v varies directly as g, and v=36 when g=4. Find v when g =11

Answers

36v.......4g

x...........11g

Cross multiply

4x= 36*11

4x= 396

x= 396/4

x= 99

When g=11 V will equal 99

I hope that's help !

you can also doing it another way

4*9= 36v

11*9= 99
