v = 17.06851cu.inches
when rounded the answer would be 20cu. inches
The formula for finding the volume of a cone is
1/3(hπr^2)
since we don't know the radius we can find it out through the equation of finding the circumference which is π x d =9.8inches
so the diameter is 9.8/π
which is 3.119437 inches
since the diameter is 2xradius so it would be
3.119437/2=1.559718
so now we can plug this into our equation

1/3(6.7x3.141592653x1.559718^2)
so that would be 17.06851cu.inches

Hitman42 [59]

Answer:Brielle will run the half marathon race faster.Brielle will take 1 hour 44 minutes and 48 seconds, Joshua will take 2 hours 37 minutes and 12 seconds

Step-by-step explanation:

10 / 1.25 = 8

8 minutes a mile

18 / 1.5 = 12

12 minutes a mile

Brielle will run the half marathon race faster.

8 x 13.1 =104.8

12 x 13.1=157.2

104.8 - 60=

44.8

60 seconds x .8= 48

Brielle will take 1 hour 44 minutes and 48 seconds

157.2 - 120 = 37.2

60 seconds x .2 = 12

Joshua will take 2 hours 37 minutes and 12 seconds

(x+5)(x-3)=y<br> How do I get y to equal 0
trasher [3.6K]

Answer:

x=-5 or x=3

Step-by-step explanation:

when multiplying anything by 0, the answer will be zero

In this case, one of the two factors has to be equal to 0

start by splitting into

(x+5) = 0

solve the equation

subtract 5 from both sides

x = -5

now, repeat for the other binomial

x-3 = 0

add 3 to both sides

x=3
