patriot [66]

№1. Given: r=8 ft, π≈3.14

C=2×π×r=2×3.14×8=50.24=50.2 ft

A=π×r²=3.14×64=200.96=201 ft²

Answer: 50.2 ft; 201 ft²

№2. Given: D=11 cm, π≈3.14

d=2r or r=2/d, so if d is 11 cm, then r is 11÷2=5.5 cm

C=2×π×r=πD=3.14×11=34.54=34.5 cm

A=π×r²=3.14×(5.5)²=94.985=95 cm²

Answer: 34.5 cm; 95 cm²

Need help fast, being timed!!
tamaranim1 [39]

Answer:

Mr. Roland’s class was more successful because his class’s lower quartile was the same as Mrs. Cai’s class’s upper quartile.

Step-by-step explanation:

From given scatter plot, we see that upper quartile of Mrs. Cai's class = 4

lower quartile of Mr. Roland’s class = 4

Both are equal so that means.

That means Mr. Roland’s class was more successful because his class’s lower quartile was the same as Mrs. Cai’s class’s upper quartile.


Hence last choice is correct.
