Solve this step by step
Kaylis [27]

Step-by-step explanation:

the formula to calculate a circumference is

x \times \pi

(consider x as the diameter)

so I'll be noting the circumference as C alongside the circle's ranking

a.

ca = 6 \times 22 \div 7 \\  = 44 \div 7

b.

cb  = 7 \times 22 \div 7 \\  = 154 \div 7 \\  = 22

c.

cc \:  = 4 \times 22 \div 7 \\  = 88 \div 7

hope I helped

X/4 + 12 = 5 please help
katen-ka-za [31]
X/4 + 12 = 5
to isolate the variable the first step is to subtract 12 from both sides
x/4 + 12 - 12 = 5 - 12
x/4 = -7
next, to get rid of the division by 4, multiply both sides by 4
(x/4)*4 = -7*4
x = -28
