Volume because of weight and surface
Answer: 318
Step-by-step explanation:
7 to the 3rd power is 343, 343 minus 25 is 318
5p+7c=2p
5p=2p-7c
7p=-7c
p=-c

The area of a right triangle with side lengths 7 and 7 is 
Answer:
The surface area is 3140 feet².
What is Surface Area?
Surface area is the amount of space covering the outside of a three-dimensional shape.
Given that:
Diameter = 20 feet
radius = 20 ÷ 2 = 10 feet
Now, Surface area will be,
=2πr²+ 2πrh
= 2 × 3.14 × (10)² + 2 × 3.14 × 10 × 40
= 6.28 × 100 + 6.28 × 400
= 628 + 25.12 × 100
= 628+ 2512
= 3140 feet²
hence, the surface area is 3140 feet².
