What is the volume of a sphere if its radius is 30

ASHA 777 [7]

Answer:

About 113,097.34 units

Step-by-step explanation:

The volume of a sphere can be found with the equation V = $\frac{4}{3}$ πr³ when r is the radius.

V = $\frac{4}{3}$ πr³

V = $\frac{4}{3}$ π(30)³

V ≈ 113,097.34 units

Need help asap !!!! It also said round to the nearest tenth

Over [174]

Answer:

4524.9

Step-by-step explanation:

Area of a parallelogram:

A = bh

A = 63 x 90

A = 5670

Area of half-circle:

A = (πr²)/2

A = (π x 27²)/2

A = (π x 729)/2

A = 729/2π

Combined:

5670 - 729/2π

If mZ1 = (4x + 2)° and m/3 = (5x – 15)", what is the value of a?

posledela

Answer:

Step-by-step explanation:

angle one and angle three are equal to each other

so if you set the equations equal to each other

(4x+2)=( 5x-15)

move the 4x the right by subtracting it giving you 1x

then add 15 to 2 giving you 17

17=1x
