Fidn volume
V=hpir^2
d/2=r
1.4/2=0.7=r
height=3.5
V=3.5*3.14*0.7^2
V=5.3851

1.5 times t=5.3851
divide both sides by 1.5
t=3.59
round
t=4

The area of the shaded region

antiseptic1488 [7]

Answer:

125.66cm²

Step-by-step explanation:

so you need to find the area of the big circle and subtract it from the area of the small circle

area of a circle= π r²

small circle: substitute in what you know

a= π x 3²

a= 28.2743

big circle: substitute in what you know

a= π x 7²

a= 153.9380

now do 153.9380-28.2743=125.6637

now round this number to the nearest hundredth:

125.66cm²

You are running a 10 mile race. You run the first 3 miles in 24.7 minutes. Your goal is to finish the race in less than 1 hour 2

alukav5142 [94]

10 miles - 3 miles = 7 miles left.

1 hour 20 minutes - 24.7 minutes= 80 minutes - 24.7 minutes
= 55.3 minutes left

Therefore, you have 55.3 minutes left to run 7 miles. But since you want to finish in LESS than 1 hour and 20 minutes, subtract the .3.

So:

7 miles = 55 minutes
1 mile x minutes

x minutes= 55 x 1 ÷ 7 miles
x minutes = 7.85
x minutes = ~ 8 minutes

Therefore you have to run every mile in ~ 8 minutes.

Hope this helps!
