Answer:
34π/3 (= 11.3 π ) mi²
Step-by-step explanation:
(see attached for reference)
area of sector is given by:
A = (θ/360) π r²
where
θ = angle of sector (given as 255°)
r = radius (given as 4 miles)
substituting the known values into the formula:
A = (θ/360) π r²
A = (255/360) π (4)²
A = (255/360) π (16)
A = 34π/3 mi²
A = 11.3 π mi²

Answer:
1-15. a: b: 42 tiles. Add 4 tiles to get the next figure. 1-16. a: x = 0 b: all real ... 3-78 does, possible response: the b in its equation is 3 versus 1 in problem 3-79. ... If x is the age of the van, then x + (x + 17) = 41 or if x is the age of the truck, then.
Step-by-step explanation:
You would do 8/9 - 3/5
convert everything to whatever/45
so 40/45 - 27/45
the answer is 13/45 of an hour.
Answer:
12
Step-by-step explanation:
x = 2n
2n + 2n + 2 + 2n + 4 + 2n + 6 + 2n + 8 = 80
10n = 60
n = 6
x = 12
12 + 14 + 16 + 18 + 20 = 80
