S=4π<span>r<span>2 - this is the equation for the surface area of a sphere. We know that the radius (r) is 3.5 so here's how to solve this:
S = 4</span></span><span>π r2
S = 4</span><span>π (3.5)2
S = 4</span><span>π 12.25
S = 49</span><span>π
The surface area of a sphere with radius of 3.5 is 49</span><span>π.</span>

Answer:
For one adult it costs $15
For one child it costs $10
Step-by-step explanation:
So..
One adult = $15
Two children = $20 10×10
= $35
Then..
Two adult = $30 15×15
Three children = $30 10×10×10
= $60
Plz mark brainliest thanks
Answer:
to be quick divide 3/4 ×100=75 percent
1/10=10
.25×100=25
0.8=80
1/2=50 so now u know which one is the smallest from largest so it is 1/10 , 0.25 ,1/2, 3/4, 0.8
