Answer:
i might be wrong but i think its 10
Step-by-step explanation:
x2+8x=9
collet terms
10x=9
divide both side by 10
x = 9/10
alternative form
x = 0.9
Answer:
16pi
Step-by-step explanation:
144pi is the area of the whole circle
(360 - 320)/360 = 1/9
144*1/9=16
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>
