1 answer:
<h3>Given:</h3>
<h3>To find:</h3>
The approximate volume of the given sphere . <h3>
Solution : </h3>
Let's substitute the values according to the formula .
Let's solve!
Now, well have to round off to the nearest hundredth .
<u>Hence,</u> <u> </u> <u>the</u> <u> </u> <u>volume</u> <u> </u> <u>of</u> <u> </u> <u>the</u> <u> </u> <u>given</u> <u> </u> <u>sphere</u> <u> </u> <u>is</u> <u> </u> <u>523.6</u> <u> </u> <u>cubic</u> <u> </u> <u>units</u> <u>.</u>
Note : If your using π as π you'll get this answer.

M∠H = 180° - ( 65° + 35° ) = 180° - 100° = 80° The Law of sines: h / sin H = g / sin G 10 / sin 80° = g / sin 35° 10 / 0.9848 = g / 0.5736 g = ( 10 · 0.5736 ) : 0.9848 = 5.736 : 0.9848 = 5.8245 ≈ 5.8 Answer: g = 5.8
Answer:
2.64cm
Step-by-step explanation:
A = π r^2
5.5 = π r^2
1.75 = r^2
r = 1.32
Diameter is then 2(1.32) = 2.64
