Answer:
4.46cm
Step-by-step explanation:
Volume of a frustum is expressed as;
V = (1/3) * π * h * (r₁² + r₂² + (r₁* r₂))
h is the height of the frustum
r₁ and r₂ are the radii of its ends
V is the volume
Given
V = 9100cm₃
r₁ = 10cm
r₂ = 30cm
Substitute
9100 = (1/3) * (3.14) * h * (10² + 30² + (10* 30))
9100 = 1/2(3.14)*h*(100+900+300)
9100 = 1.57*h*(1300)
9100 = 2,041h
h = 9100/2,041
h = 4.46cm
Hence the height of the cap is 4.46cm
Answer:
8x-29.6
Step-by-step explanation:
evenly distribute the 8 throughout the parentheses.
8 times x
8 times -3.7
(i hope this is right, i don't know if there was more context)
Answer:
Interest = $240
Ending Balance = $990
Step-by-step explanation:
Applying I = prt/100
= (750*4*8)/100
= 240
Therefore Interest = $240
Adding Interest to Principal
= $240 + $750 = $990
=
If you divide the age by the height the quotient is 3.57 in each case so it is direct variation
C is correct
Answer:
x=17
Step-by-step explanation:
7x+10+3×=180
10x+10=180
-10. -10
10x/10=170/10
x=17
