27 because 18 divided by 2 is 9 so you just add 9 more to $18
Answer:
The answer is
<h2>1520.5 cm²</h2>
Step-by-step explanation:
Surface area of a sphere is given by
S = 4πr²
where r is the radius
From the question r = 11cm
So the surface area of the sphere is
4π(11)²
= 4(121)π
= 484π
= 1520.5308
Which is
1520.5 cm² to the nearest tenth
Hope this helps you
Answer:
it's 8-3m
Step-by-step explanation:
3m^2+2p^2-15
3(3)^2+2(10)^2-15
3(9)+2(100)-15
21+200-15
206
<span>If you pull the edges of the right angle down it makes a straight line.
Therefore, the angles in a triangle add up to 180°
So, 35 + 45 = 80
Then, 180 - 80 = 100
The third angle = 100° </span>
