In order to find the length of the hypotenuse, we use knowledge on trigonometric functions which would be sine and is expressed as:
sine (theta) = opposite side / hypotenuse
sine 80 = 4 / hypotenuse
Hypotenuse = 4.1 in <---- OPTION B
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
Answer:
Step-by-step explanation:
We can use the general distance formula between any two points 
and 
on the plane given by:
We simply identify with (0, 4) and with (-6, -3) , thus obtaining:
