The volume of the sphere is calculated through the equation,
V = 4πr³/3
Substituting,
900 in³ = 4πr³/3 ; r = 5.99 in
Then, solve for the surface area of the sphere by the equation, SA = 4πr²
SA = 4π(5.99 in)² = 450.80 in²
Thus, in the nearest whole number, SA was calculated to be nearly 451 in².
Answer:
The answer would be left 2
Step-by-step explanation:
Answer:
61 + x
The sum of two valies are what you get if you add them together. So the sum of 61 and x is written as 61 + x
1/4z + 8 = 12
1/4z = 12 - 8
1/4z = 4
z = 4 / (1/4)
z = 4 * 4/1
z = 16 <===
==================
-3(2n + 1) + 7 = -5
-6n - 3 + 7 = -5
-6n + 4 = -5
-6n = -5 - 4
-6n = -9
n = -9/-6
n = 3/2 <===
===================
2.5(t - 2) - 6 = 9
2.5t - 5 - 6 = 9
2.5t - 11 = 9
2.5t = 9 + 11
2.5t = 20
t = 20 / 2.5
t = 8 <===
