Answer:
- 3.24 m²
- 156 cm²
Step-by-step explanation:
1.
Area of a parallelogram = base × height
The area of the parallelogram
= 2.7 × 1.2
= <u>3.24 m²</u>
2.
Try to divide the figure into 2 rectangles and find their areas.
The area of the larger rectangle
= 6 × (20-6)
= 84 cm²
The area of the smaller rectangle
= 12 × 6
= 72 cm²
The total area of the figure
= 84 + 72
= <u>156</u><u> cm²</u>

Just trust me btw i'm too lazy to write a step-by-step
Answer:
Given differential equation,
Taking integration both sides,
Put 7 - 5y = u ⇒ -5 dy = du ⇒ dy = -du/5,
Here, x = 0, y = 0
Hence, from equation (1),
Volume of a cone = (1/3) x Area of the base (B) x height(h)
V = (1/3)·420·180
= 25200 mm³
