One formula for the surface area (S) of a prism is
S = 2(LW + H(L+W))
Filling in the given values, you have
S = 2((8 cm)·(6 cm) + (24 cm)·(8 cm + 6 cm))
= 2(48 cm² + (24 cm)·(14 cm))
= 2·384 cm²
= 768 cm²
The surface area is 768 cm².
The longer the bridge the more weak it will be. The shorter the bridge the stronger it will be.
Hello! :)
<h2>Answer:</h2>
All of the following statements about the cone are true.
2.) The radius is 9 mm.
3.) The base area is calculated using the radius.
4.) The volume is one-third the volume of a cylinder with the same height and diameter.
5.) The volume of the cone is 297 pi millimeters cubed.
<h2>Explanation:</h2>
The radius is always half the diameter, which is why the first choice is false, and the second choice is true.
When calculating the base, you need to use the radius. This means the third choice is true. The formula for the base area is π
Volume of the cone:
V =
π
h
=
× π ×
× 11
= 933.052233 mm²
Volume of a cylinder with the same height and diameter:
V = π
h
= π × 81 × 11
= 891π
= 2799.15669 mm²
2799.15669 ÷ 3 = 933.052233
Option four is true.
297 × π = 933.05223 This is true.
Information given:
- <u>100 passengers in each train car</u>
- <u>10 train cars total</u>
- <u>30 trains total</u>
<em>So we are trying to find the total number of passengers on all 30 trains?</em>
<u />
Step-by-step:
100 x 10 = <u>1,000 passengers per train</u>
1,000 x 30 = <u>30,000 passengers total within the 30 trains</u>
Answer: <u>30,000 passengers</u>
<em>Hopefully this answered your question :)</em>
Y=15/x or xy=15 it seems that a should be 15/x
