We are given area of the spherical lampshade = 57.76 \pi square inches.
We know formula of area of a spherical shape:

Plugging area A= 57.76 π in formula, we get

Dividing both sides by 4π, we get


Taking square root on both sides, we get

r =3.8.
<h3>Therefore, the radius of the lampshade is 3.8 inches.</h3>
Answer:
second option
Step-by-step explanation:
Pythagoras for right-angled triangles :
c² = a² + b²
c is the Hypotenuse, the line opposite of the 90 degree angle.
a and b are the other 2 sides.
the distance between 2 points is the Hypotenuse of a right-angled triangle of the coordinate differences in x and y.
so, we have (-2, -3) and (3, 2)
distance² = (x1 - x2)² + (y1 - y2)² = (-2 - 3)² + (-3 - 2)² =
= (-5)² + (-5)² = 25 + 25 = 2×25 = 50
distance = sqrt(50) = sqrt(2×25) = 5×sqrt(2)
Answer:
35 degrees
Step-by-step explanation:
All three angles must add up to 180 degrees
55+90=145
180-45=35
Answer:
4
Step-by-step explanation:
Okay, so the first step is to divide 30 and 5. You should get 6.
Then all you have to do is divide 24 and 6. You should get 4.
I believe CAB is 111 because 111+69 = 180
