Answer:
Step-by-step explanation:
larger radius R=87/2
smaller radius r=65/2
larger semi circle=1/2×2×π×R=π×R=π×87/2=87 π/2≈136.6 m
smaller semicircle =π×r=π×65/2=65 π/2≈102.1 m
length of track=87+65+136.6+102.1≈390.7 m
Everyone works differently in mental meth.
To calculate 9*52, we note that 9=10-1, so mentally calculate
9(52)
=(10-1)(52)
=520-52 [ subtract 20 from each number]
=(520-20)-(52-20)
=500-32
=468.
Alternatively,
9*52=9*50+9*2=450+18=468
If you're good with multiplication and division,
9*52=3*3(52)=3*156=450+18=468
Answer: ((T/(2pi))^2)g
Step-by-step explanation: just solve for L
I don't know how to solve this but if you private message me I have another way for you to find out....
Answer:
D. 296.00 LBS
Step-by-step explanation:
We convert both heights to inches.
1 ft = 12 in.
5 ft 3 in = 5 × 12 in. + 3 in. = 63 in.
6 ft = 6 × 12 in. = 72 in.
