Answer:
V=πr^2h
pi = 3.14
r = 2
r^2 = 4
h = 10
Multiply all the numbers to get the volume.
Or use the formula.
V = 3.14*4*10
V = 125.6 cubic inches
2/8 divided by 1/4. Steps: 1. Division in math actually means multiplication. You just have to multiply by the reciprocal of the second fraction (reciprocal= denominator and numerator are switched). 2. Do 2/8 times 4/1. 3. 2 times 4= 8 and 8 times 1= 8
4. Your answer would be 8/8 which equals 1. This is how you divide fractions

Answer:
A. 17
Step-by-step explanation:
using the cosine rule (also see attached for reference):
AB² = BC² + AC² - 2·AC·BC cos C
2·AC·BC cos C = BC² + AC² - AB²
Given that AC = 18, AB = 12 and BC = 18, substituting these into the formula
2(18)(28) cos C = 28² + 18² - 12²
1008 cos C = 964
cos C = 964/1008
cos C = 0.9563
C = cos⁻¹ 0.9563
C = 16.99 ( = 17° rounded to nearest degree)
