3x(8r-1) x (4r+2s)
3x7r x (4r+2s)
21r x (4r+2s)
Answer:
A
Step-by-step explanation:
The base is the circle.
To find the area of the circle, use pi*r^2
pi = 3.14
r = 6
- Area = 3.14 * 6^2
- Area = 3.14 * 36
- Area = 113.04
Because the left side sqrt is multiplied by 3 if it was just added it would be correct because it would cancel out and leave the 3’s. Since it’s multiplied it would change the value
Answer:
Step-by-step explanation:
The formula for the surface area is A = 4πr². This formula can be solved for r² and then the result solved for the radius, r:
A
r² = -------- The radius of the sphere is as follows:
4π
√(30 m²)
-------------- meters
2√π
To find slope use the slope formula. Then, use y=mx+b. Plug in the numbers.
