3 ft
Area: 1
Circumference:
Х

Step-by-step explanation:

circumference of a circle :

2×pi×r

area of a circle

pi×r²

r(radius) is diameter/2. = 1.5ft

we shall assume 3.14 to be pi.

so,

circumference is

2 × 3.14 × 1.5 = 3.14 × 3 = 9.42 ft

area is

3.14 × 1.5² = 3.14 × 2.25 = 7.065 ft²

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9
