Answer:

Area = 452.16 cm²

Volume = 904.32 cm³

Step-by-step explanation:

The solid is a sphere, therefore,

Volume = ⁴/3πr³

Where,

π = 3.14

r = 6 cm

Volume = ⁴/3*3.14*6³

Volume = 904.319997 ≈ 904.32 cm³ (nearest hundredth)

Area = 4πr²

Area = 4*3.14*6²

Area = 452.16 cm²

Answer:

$x+7=4x-11$

Step-by-step explanation:

Hi there!

Let $x$ represent "the number".

A number added by 7 is the same as that number times four minus eleven.

A number added by 7 ⇒ $x+7$

Is the same as ⇒ $x+7=$

The number times four ⇒ $x+7=4x$

Minus eleven ⇒ $x+7=4x-11$

I hope this helps!

What is the approximate area of the shaded sector?

kodGreya [7K]

Answer:

C. $302 \: {cm}^{2}$

Step-by-step explanation:

$Area \: of \: sector = \frac{ \theta}{360 \degree} \times \pi {r}^{2} \\ \\ = \frac{135 \degree}{360 \degree} \times \pi {r}^{2} \\ \\ = \frac{135 }{360 } \times 3.14 \times {(16)}^{2} \\ \\ = \frac{108,518.4 }{360 } \\ \\ = 301.44 \\ \\Area \: of \: sector \approx \: 302 \: {cm}^{2}$
