Answer: i think that is the ans
Step-by-step explanation:
Answer:
The volume = 523.3 ft.³
Step-by-step explanation:
∵ Surface area of the sphere = 4πr²
∴ 4πr² = 100π
∴ 4r² = 100 ⇒ r² = 100/4 = 25
∴ r = √25 = 5 ft.
∵ Its volume = 4/3 πr³
∴ Its volume = (4/3) × π × 5³ = 523.3 ft.³
<span>First set: 7, 24, 25.
Square 7, 24 and 25.
Add together the squares of 7 and 24.
Compare this sum to the square of 25. </span>
The answer is x = 3, as we know that the measure of vertical angles are equal. This means that 2x = x + 3, so x = 3.<span />
