Hi there!

I believe your answer is:

$6525\text{cm.}^3$

Keep in mind that this is APPROXIMATE.

Here’s why:

⸻⸻⸻⸻

$\boxed{\text{Volume of a Sphere Is:}}\\\\V = \frac{4}{3} \pi r^3\\----------------\\\rightarrow \text{We are given the radius of } 11.6\text{ cm.}\\----------------\\V = \frac{4}{3}(3.14) (11.6)^3\\\\V = \frac{4}{3}(3.14) 1560.896\\\\V \approx 6534.95125\text{cm.}^3\\\\\boxed{V \approx 6535\text{cm.}^3}$

75 = 4(2)^x

Valentin [98]

Answer:

4.229

Step-by-step explanation:

75 = 4(2)^x

75/4 = 2^x

Apply ln both sides

ln(75/4) = ln(2^x)

ln(75/4) = x ln(2)

x = ln(75/4) ÷ ln(2)

x = 4.22881869

angle 1 and Angle 2 are corresponding angles. app they are equal.

73-2x = 88-3x

x = 15

angle 1 = 73-(2*15) = 43

angle 2 = 88-(3*15) = 43
