Estimate the diameter of a circle with a circumference of 80 feet. 50.96 ft 12.74 ft 25.48 ft 40 ft

Using the circumference of the circle formula..

C = πd

Given that C = 80..

80 = πd

d = 80/π ft

≈ 25.4 ft

Circumference = π * diameter

diameter = Circumference / π

= 80 / π

= 25.48  feet

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93

i am not sure
