Answer:
Area = PI * radius^2
radius = Sq Root (Area / PI)
radius = Sq Root (78.5 / PI)
radius = Sq Root (24.9873260654)
radius = 4.9987
radius = 5 (rounded)
Step-by-step explanation:
<span>PQR is a triangle
QR = x </span>⇒ x>0
If x>0 then:
QR is the smallest side
PQ is the largest side
<span>In the triangle, the largest angle lies opposite the largest side.
</span>The angles of Δ<span>PQR in order from largest to smallest:
</span>∠R is largest [opposite to PQ]
∠Q is middle [opposite to RP]
∠P is smallest [opposite to QR]
Ok, so amy is 8 years older than twice alica's age
if amy=y and alica=x
y=8+2x
and sum is less than 32
y+x<32
we can subsitute 8+2x for y in other equation
8+2x+x<32
8+3x<32
minus 8 both sides
3x<24
divide both sides by 3
x<8
the inequality is x<8
