I’m sorry if this is so simple but i’m not good at this stuff at all

what is the area of a circle with a radius of 40 cm?
(use 3.14 for pi.)

Area=Pi*radius squared

40 squared is 1600

1600*3.14=5,024 cm squared

the correct answer should be 50.24 mm2 hope it's right

Step-by-step explanation:

Area of circle

= ∏ r2

= 3.14 × (4 × 4)

= 50.24 mm2

answer: 0,6

step-by-step explanation:

this would make it the y intercept.

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
