Answer:
<h2>R = 16 in</h2>
Step-by-step explanation:
The formula of a Surface Area of a sphere:
![S.A.=4\pi R^2](https://tex.z-dn.net/?f=S.A.%3D4%5Cpi%20R%5E2)
R - radius
We have
![S.A.=1024\pi\ in^2](https://tex.z-dn.net/?f=S.A.%3D1024%5Cpi%5C%20in%5E2)
Substitute:
<em>divide both sides by π</em>
<em>divide both sides by 4</em>
![R^2=256\to R=\sqrt{256}\\\\R=16\ in](https://tex.z-dn.net/?f=R%5E2%3D256%5Cto%20R%3D%5Csqrt%7B256%7D%5C%5C%5C%5CR%3D16%5C%20in)
Answer:
Area of the triangle is 121 cm²
Step-by-step explanation:
To solve this, we will follow the steps below;
We will first find the height of the triangle, from the diagram below:
opposite = h where h is the height of the triangle
adjacent = 7
Ф=68°
Using trig.ratio
tan Ф = opposite/adjacent
tan 68° = h/7
h = 7 tan 68° = 17.33
height of the triangle =17.33 cm
From the question, base(b) = 14 cm
Area of a triangle = 1/2 × b × h
=1/2×14×17.33
=121.31
≈ 121 cm²
Area of the triangle is 121 cm²
Plug in 4 for x.
f(x) = 2x - 10
f(4) = 2(4) - 10
Simplify. Remember to follow PEMDAS. First, multiply, then subtract
f(4) = 8 - 10
f(4) = -2
-2 is your answer for f(4)
~
20 + 5 + 500,000,000 = 500,000,025
500,000,025 - 200,000 = 499,800,025
So Johny has 499,800,025
Tommy has 100,005
And Tommy's sister has 100,020
Hope it helps!
Answer:
6*108>3*106
Step-by-step explanation:
If you multiply 6, and 108, you would get 648.
And if you were to multiply 3 and 106 you would get 318. And 648>318.
Therefore, 6*108>3*106
