8x10^3 is 20 times larger than 4x10^2.
Your volume formula is not correct.
anyway volume = 1/3 * h * r^2*pi, this liquid volume is constant regardless of the container.
so plug in h and r, v = 1/3 * 6 * 3^2 *pi= 18pi
cylinder is just area of circle * h, so
pi*r^2*h = 18 pi
r^2*h= 18
3*3*h=18
h = 2
<span>basically set the volume equal to each other, and plug in r, and solve for H in cylinder eqn</span>
Actually Welcome to the Concept of the SURFACE AREAS AND VOLUMES.
Since the given section is a Sector of a Circle with length as, 8πcm .
Thus then it's folded veltically at an axis to make a cone.
since we know that, The Curved surface area of a cone is given as formula,
C.S.A = πrl
where, r = radius and l = slant height.
also 2πr = circumference of a circle,
we get as, radius = 4 cm.
Answer:
£223 was the original price
Step-by-step explanation:
35% of original price = £78
1% of original price = £78/35 = £2.23
100% of original price = 2.23 x 100 = £223
