Answer:
1.48
Step-by-step explanation:
Formula:
degrees × (π)/180
85 × (π)/180
85π/180
17/36π
1.483
Rounded to nudredths: 1.48
Answer:
6 inches
Step-by-step explanation:
The formula for volume is length*width*height. Following this,
7*4*h=168
28h=168
h=6
Area=width*height
area=(11.7)*(15.4)
area=180.18cm^2
Answer:
A=48.81
Step-by-step explanation:
it is a right angle triangle find the hypotenuse c using Pythagorean theorem:
c²=a²+b²
c²=8²+7²
c=√64+49
c=10.63
sin A =opp/hyp
sin A=8/10.63
A= 48.81
another way :
tan A=opp/adj
tan A=8/7
A=48.81
Circumference = 2πr
6.28 = 2πr
12 = 2n/3 +7n/3 -6
6.28 = 2×3.14×r
r =6.28/2×3.14
r= 1 unit
Now,
Area of a circle = πr² = 3.14×1×1= 3.14 sq.units
