Answer:
927.0 cm²
Step-by-step explanation:
Step 1: find Z
m < Z = 180 - (28 + 118) (sum of ∆)
= 180 - 146
Z = 34°
Step 2: Find side XY using the law of sines
Cross multiply
Divide both sides by 0.469
XY ≈ 50 cm
Step 3: find the area.
Area of ∆ = ½*XY*YZ*sin(Y)
XY ≈ 50 cm
= ½*50*42*sin(118)
= 25*42*0.8829
Area = 927.045
Area ≈ 927.0 cm² (nearest tenth)

Write an equation in point slope form
The point slope form of an equation is:
Substitute values for y1, x1 and m
Hence, the equation in point slope form is:
Answer:
1130.97336 units^3
Step-by-step explanation:
The volume of a cylinder can be found using:
We have the area of the base, but not the radius
We know the area is , so we can substitute that in for a
We want to find r, so we need to isolate it
Divide both sides by pi
36=r^2
Take the square root of both sides
6=r
Now we know the radius, and can substitute it into the volume formula, and we can substitute the height (10) in
Solve the exponent
v=1130.97336
The volume is 1130.97336 units^3
#To make a fraction into percentage, the easy way is to times the fraction with 100
<h3>The percentage of 9/10</h3>
9/10 × 100 = 90
#and so, the percentage of 9/10 is 90%
<h3>
Answer : 90%</h3>
