I believe it would be 6 due to the radius being a half of the actual circumfrence

The relation between perimeter and radius  is P = 2 pi r

dP/dr = 2pi

dP/dt = 3  

when r = 2   dr/dt  = dP/dt * dr/DP =  3 * 1/2pi  = 0.477  m/s

Find the x is qs bisects pqr and pqr=82
slavikrds [6]

if ∡PQR = 82°, and the ray QS bisects it, it cuts ∡PQR into two equal halves, ∡PQS and ∡RQS, each of which is then 82/2, or 41°.


\bf \stackrel{\measuredangle PQS}{10x+1}=41\implies 10x=40\implies x=\cfrac{40}{10}\implies x=4

T/2 + 3 = 5 (solve for t)
Mashutka [201]

Answer:

t = 4

Step-by-step explanation:

Given

\frac{t}{2} + 3 = 5 ( subtract 3 from both sides )

\frac{t}{2} = 2

Multiply both sides by 2 to clear the fraction

t = 2 × 2 = 4
