Answer:
14
Step-by-step explanation:
area of sector = 153.9
or, (1/2) r²∅ = 153.9
or, r²∅ = 153.9 ×2
or, r²∅ = 307.8
or, r²× π/2 = 307.8
or, r² = 615.6/π
or, r² = 196
or, r=√196
r = 14

Answer:
it is 1526.81 NEAREST 10= 1530ft^3
Step-by-step explanation:
V=πr2h is the formula...
For a single payment with compound interest, the equation to use is F=P(1+i)^n where F is the value after n periods, P is the present value, and i is the interest rate.
If we want the final value F to double given 5% per year interest, F=2P then i=5.
Solving for n:
2P=P(1+0.05)^n
2=(1.05)^n
log(base 1.05)2=n
n=14.206=14.21 years
B) (4,1) the solution to the graph is where the two lines intersect
