Answer:
49Pi cm^2
Step-by-step explanation:
Area of a circle = Pi r^2
Radius r = 7
Area = Pi x 7^2
= Pi x 7 x 7
= 49Pi cm^2
The value of y is positive 8
34.4 ÷ 4 = 8.6, which 8.6 as a fraction is 43/5
The value of x in tan(x)=sin38° is 31.6 and the value of x in cosec(x+10°)=1.345 is 38.0
<h3>How to solve the trigonometry ratios?</h3>
The equations are given as:
tan(x)=sin38°
cosec( x+10°)=1.345
In tan(x)=sin38°, we have:
tan(x)=0.6157
Take the arc tan of both sides
x = 31.6
Also, we have:
cosec(x+10°)=1.345
Take the inverse of both sides
sin(x+10°) = 0.7434
Take the arc sin of both sides
x+10 = 48.0
Subtract 10 from both sides
x = 38.0
Hence, the value of x in tan(x)=sin38° is 31.6 and the value of x in cosec(x+10°)=1.345 is 38.0
