Answer:
6
Step-by-step explanation:
In y = Asin(Bx + C) +D,
|A| is the amplitude
Amplitude: |-6| = 6
I apologise, but it is as though that there is some missing necessary information. Perhaps there was an error?
Given:
Volume of toy=231 cm³
Diameter of a hemisphere= 7 cm
cone and hemisphere have equal radius.
radius of hemisphere = radius of cone = 3.5 cm
Height of hemisphere= radius of hemisphere= 3.5 cm
Let H be the height of toy
H= height of cone+ height of hemisphere
H = h + r , ( h = height of cone)
H = h + 3.5
volume of toy = volume of cone + volume of hemisphere
Volume of toy= 1/3πr²h + 2/3πr³
Volume of toy=πr²/3(h+2r)
231 = (22/7)×(3.5)² ×(1/3)(h+2×3.5)
231×3 =( 22×3.5×3.5)/7 (h+7)
h+7 = (231×3×7)/(3.5×3.5×22)
h+7 = (3×3)/(.5×.5×2)
h+7= 900 /50= 90/5= 18
h+7= 18
h=18-7
h= 11 cm
Height of toy = h+r
Height of toy = 11+3.5= 14.5
Height of toy =14.5 cm
Hence, the height of the toy = 13.5 cm
Answer + step-by-step explanation:
Hi forschoollol027!
I recommend finding the squareroot of 24 because
in a sqaure all of the sides are equivalent to each other
The sqaureroot of 24 is a decimal answer so you could
try rounding it off. Either way, the sqaureroot of 24 (which
is what I think is the answer) is 4.89897949. Rounded to one
decimal place = 4.8, rounded to two decimal places = 4.89.

We can compare the two units or object performances by that.... even in the case of magnitude lower than zero....
