What is the area of a circle if the diameter is 40 meters PLEASE HELP PLEASE IM TIMED

it would be 400

Step-by-step explanation:

just add 360 + 40 and u get 400

Dont quote me on this bc idfk

Half of 40 is 20(new radius)

20^2 = 400

400 x 3.14 = 1256 meters^2

Formula of area of a circle:

πr2

pi(3.14 or 22/7 whatever they tell you to use for pi) x radius(half of your diameter or your given radius) being squared(^2 to the power of 2)

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

the reporter's right

step-by-step explanation:

1/4 = .25 / 25%
