Answer:
C=2πr=2·π·41≈257.6106
Step-by-step explanation:
The value of the angle R in the right triangle PQR is sin⁻¹ 6 / 8
The situation forms a right angle triangle.
<h3>How to find an angle in a right triangle?</h3>
The angle R can be found as follows:
using trigonometric ratios,
sin R = opposite / hypotenuse
Therefore,
opposite sides = 6
hypotenuse = 8
sin R = 6 / 8
R = sin⁻¹ 6 / 8

Answer:
I think is 12.5
Step-by-step explanation:
25 times 0.5 is 12.5
144+64= 178

a^2+b^2= c^2
Whenever finding a missing length use the formula up above :
a^2+b^2= c^2
a^2-b^2= c^2
144-64= 80
