Answer:
7/3
Step-by-step explanation:
Keep Change Flip -KCF (not to be confused with kfc )
7/8 x 8/3
Keep Change Flip in other words, keep the <u>first fraction</u> change from <u>division to multiplication</u> (since multiplication is the opposite of division) and flip the <u>second fraction</u>
The formula for the circumference of a circle is
C = 2π·r
or
r = C/(2π)
The radius r of cylinder A is
r = (4π)/(2π) = 2
The formula for the area of a circle is
A = π·r²
or
r = √(A/π)
The radius of cylinder B is
r = √(9π/π) = 3
The dimensions of cylinder A must be multiplied by 3/2 to produce the corresponding dimensions of cylinder B.
Answer:
He should buy 189.47 feets.
Step-by-step explanation:
Since there's a hypotenuse this triangle is rectangular and since it's an isosceles triangle we know that both cathetus are equal. We were given the area of this triangle, wich is 4500 square feet, the equation to compute this area is A = b*h/2, since the cathetus are equal b = h and we can solve for either of this variables. So we have:
A = b*b/2
4500 = b*b/2
b*b= 9000
b = sqrt(9000) = 94.87 feet
Since the hypotenuse of this triangle already has a fence we only need to buy the fencing for the cathetus, wich should be two times b, since there are two cathetus. So the amount of fence is 2*b = 2*94.87 = 189.74 feets.
Answer:
D. [0,pi/2]
Step-by-step explanation:
when Ф = 0 in radian
r²= 4cos (2(0))
r² = 4 * 1
r² = 4
∴ r = √4 = 2
r = 2.
when Ф = π/2 in radian
r²= 4cos (2(π/2))
r² = 4 * -1
r² = -4
∴ r = 0
