Answer:
Step-by-step explanation:
1.
c.r.=10.5/10=105/100=21/20
or 10.5/10=1.05
2.
c.r=9/27=1/3
3.
c.r.=(3/4)/1=3/4
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>
