Look up the.name of the book online with anser sheet I had that same book just find the page
Answer:
16/45
Step-by-step explanation:
4/9 x 4/5=16/45 you just multiply straight across
Circumcerence = distance travelled in one full rotation = 2 x π x 8 = 16π
for 2 minutes and 15 seconds,
multiply 16π by 2.25 as 2 minutes is twice the distance of one rotation and 15 seconds is a quarter more
therefore answer is 36π = 113.1 inches
9 = 20 = 100 = 10 = -8 =
-24 = -18 = -16 = -38 =
Circumference = 2pi * r
So
3pi = 2pi r divide away pi
3 = 2 r
(3/2) = r = 1.5 m
Area = pi ( r^2) = pi (1.5)^2 = 2.25 pi m^2 ≈ 7.07 m^2
