—radius is 1/2 the diameter so if the diameter is 6, the radius would be 3.
—the circumference is 2pier
so you would use your calculator and use the pie symbol or 3.14 and multiply 2*3.14*3 (3=radius for my example)
— the area is pie r^2
so you would multiply 3.14*3 squared

Answer:

Step-by-step explanation:

According the Triangle sum theorem:

m<T + m<U + m<V =180

x + 2x + x + 80 = 180

solve: x=25

Therefore m<T = 25, m<U = 50, and m<V = 105

Cscx/secx = cotx<br><br> Verify with steps please :)
Dovator [93]
Csc(x) = 1/sin(x)
sec(x) = 1/cos(x)
cot(x) = [1/sin(x)] / [1/cos(x)] 
cot(x) = 1/sin(x) * cos(x)/1
cot(x) = cos(x) / sin(x)
cot(x) = cot(x)
