Answer:
a. Triangular prism , b. 157.5cm squared , c. 369cm ,d. 405 cm cubic
Step-by-step explanation:
b. I assume lateral meabs the area which is visible ( exclude dotted lines)
c. sum of areas of all 5 shapes used to make the triangular prism ( L×W ) + l×w +l×w + 1/2×bh +1/2×bh
d. volume = AREA OF CROSS SECTION(which is a triangle) ×LENGHTH or Height(6cm)
To work out the volume of a prism, you multiply the area of cross-section by the height (or length).
So for a cylinder, you work out the area of the circle and then multiply it by the height.
Area of circle (or cross-section) = π × radius²
= π × 0.7²
= 0.49π m²
Now to get the volume of the cylinder, you times this area of the cross-section by the height of the cylinder:
Volume = 0.49π × 1.5
= 2.3 m³ (accurate to 2 decimal places)

Answer:
The maximum volume of rainwater the cylinder can hold is:
<u> </u><u>2.3 </u><u>m³</u>
Answer: 0.0265
Step-by-step explanation:
Given: The proportion of Mississippians live in poverty, which makes Mississippi the state with the highest poverty rate in the United States. : p = 19.7% = 0.197
Sample size : n= 250
The probability that at least 25% of them live in poverty will be
Hence, the required probability = 0.0265
18, you have 3 choices for the bottom because you can't use the small one, 3 choices for the next because you can now use the small one, 2 for the next and finally 1. You multiply all of them to get 18
