The distance around a meteor crater is 9,799 ft. Find the diameter of the crater. Use 22 7 for π.
madam [21]

Answer:

3118.7ft

Step-by-step explanation:

Given data

Circumference=  9,799 ft

We want to find the  diameter, but we need to get the radius

C= 2πr

9,799=2*22/7*r

9,799=2*3.142*r

9,799=6.284r

r=9,799/6.284

r= 1559.35

Hence the diameter is =1559.35*2

Diameter=3118.7ft

What's the area of this? PLS HELP
balandron [24]

Answer:

446mm

Step-by-step explanation:

If we box off parts of the area, it makes it easier to solve. I personally broke it into tiny bits:

Upper left box: 16mm

Bigger box (excluding little box): 90mm

Big rectangle: 340mm

Now, add them all together.

Equals 446mm

I can't fail and no one has answered my previous questions so please help.
Afina-wow [57]
When you know your equation f(x) and they want you to find f(-4), it means that they want to know what f(x) is worth when x=-4 Therefore, you only need to plug in you x in the equation f(x)=5x-2 f(-4)=5(-4)-2 =-20-2 =-22 (B)
