Answer:
93214.28 cm³
Step-by-step explanation:
The area of the given solid in the front side is = area of the rectangle + area of the semi circle.
= ( 40 × 30 ) + 0.5 × π × r²
= 
{Since radius = 0.5 × Diameter = 0.5 × 30 = 15 cm}
= 1553.57 cm².
Now the volume of the solid is given by (Area of the vertical surface × horizontal length) = 1553.57 × 60 = 93214.28 cm³ (Answer)
If you would like to know how many solutions does the system of two equations have, you can calculate this using the following steps:
x = -4y + 4 ... x + 4y = 4 /*(2)
2x + 8y = 8
____________
2x + 8y = 8
<span>2x + 8y = 8
</span>____________
0 = 0
The correct result would be infinitely many solutions.
Pure gold is 24 karats.
14-karat gold is 14/24 pure gold.
2.5 oz * 14/24 = 1.458333... oz
Answer:
63.6m²
Step-by-step explanation:
The radius is 4.5m because it's half of the diameter.
Area = πr²
Area = π(4.5)² = 63.6m²
