Answer:
_____________the answer is (-7,-3)______________
Answer:
C. c^2=a^2+b^2-2abcos(90°)
Step-by-step explanation:
This is the law of cosine.
2(pi)r = 9.4in
(pi)r = 4.7in
3.14r = 4.7in
r = 1.497in
Surface Area Of a Sphere = 4(pi)r^2 = [4(3.14)(1.497)^2]in^2 = 28.147in^2 = 28in^2
Volume Of a Sphere = 4/3(pi)r^3 = [4/3(3.14)(1.497)^3]in^3 =14.05in^3 = 14in^3
360°-90°(right angle)-90°(right angle)-52°=128°
X=128°
Hope this helps :)
