Answer:
3285
Step-by-step explanation:
5x3144=15720
3990
15720+3990=19710
19710/6=3285
The answer is "I" or "I and II".
Answer:
8
Step-by-step explanation:
∠1 = (6x + 2)° (vertically opposite angles are equal)
15x + 10° +∠1 = 180° (co-interior angles are equal)
15x + 10° + 6x + 2° = 180°
15x + 6x + 10° + 2° = 180°
21x + 12° = 180°
21x = 180° - 12°
21x = 168°
x = 168/21
x = 8
hope u understood!
step 1 :
Because soccer ball is in the shape of sphere, we can use the formula of volume of a sphere to find volume of the soccer ball.
Write the formula to find volume of a sphere.
V = <span>4/3 · ∏r</span>³ ----- (1)
Step 2 :
To find the volume, we need the radius of the sphere. But, the diameter is given, that is 24 cm. So, find the radius.
r = diameter / 2
r = 24/2
r = 12
Step 3 :
Plug ∏ ≈ 3.14 and r = 12 in (1).
<span>V ≈ 4/3 </span>· 3.14 · 12³
Simplify.
<span>V ≈ 4/3 </span>· 3.14 · 1728
<span>V ≈ 7,234.6</span>
<span>Hence, the volume of the soccer ball is about 7,234.6 cubic cm. </span>
