Answer:
radius=9cm
d=18 cm
Step-by-step explanation:
∅=l/r
∅=360-120=240°=240×π/180=4/3 π
4/3 π=37.68/r
r=37.68 ×3/(4π)=9.42×3/π=28.26/π ≈9 cm
d=2×9=18
4.
area of sector=πr²×∅/2π=r²∅/2
75.36=12² Ф/2=72 ∅
∅=75.36/72 =6.28/6=3.14/3≈1.0 467 radians.
l=r∅=12×3.14/3=12.56
length of arcNRP=12.56 cm
m ∠NQP=π/3 radians
Answer:
the total amount received is $9,630
Step-by-step explanation:
The computation of the total amount received is shown below:
= Investment made + simple interest
= $9,000 + ($9,000 × 7% × 12 months ÷ 12 months)
= $9,000 + $630
= $9,630
hence, the total amount received is $9,630
Answer: divide -6 by -2. 3
Answer
s = 11
Step-by-step explanation:
Find the value of S:
57 + s = 68
Substract 57 from both sides of the equation
s = 68 - 57
s = 11
Answer:
