To evaluate the radius of the cone we proceed as follows:
V=1/3 πr²h
plugging in the values, v=88π, h=8 ft
step 1
88π1/3πr²(8)
step 2
88π=8/3πr²
step 3
divide both sides by π
88=8/3r²
multiply both sides by 3/(8)
88(3/8)=r²
step 4
simplify
33=r²
step 5
get the square root
r=√33
Thus the mistake that Fatima made was:
<span> In step 3, Fatima did not multiply 88 by the reciprocal of 8/3 </span>
Answer:
the fraction form of 0.333 is 1/3
Because without place value you might put the decimal in the wrong place and that will effect the answer big time.
Answer:
The solution to the given inequality is a > 8.
Step-by-step explanation:
For this problem, we have to solve for the inequality.
9a - 24 > 48
add 24 on both sides of the inequality.
9a > 72
Divide 9 on both sides of the inequality.
a > 8
So, your solution would be a > 8.
Answer:
38 meters below sea level.
Step-by-step explanation:
if the sub dives 155 BELOW sea level, this equals -155.
then it RISES 117 meters, which equals +117.
we can make this into an equation
-155+117=-38!
the location of the sub is 38 meters below sea level.
