-2c = pm2 - n
Which equation is solved for m?
Answer:
d = 8
Step-by-step explanation:
Given
8 + 4d = 5d ( subtract 4d from both sides )
8 = d
Answer:
d=8
Step-by-step explanation:
8+4d=5d
1. subtract 8 from both sides > 8+4d-8=5d-8
2. simplify > 4d=5d-8
3. subtract 5d from both sides > 4d-5d=5d-8-5d
4. simplify again > -d = -8
5. divide both sides by -1 > -d/-1 = -8/-1
6. simplify again > d=8
a. 982 sq. cm
C. 314 sq.cm
b. 1481.34 sq.cm
d. 628 sq. cm
Answer:
314cm²
Step-by-step explanation:
Surface area(sphere) =4πr²
4 * 3.14 * (5²)
4 * 3.14 * 25
Hence, Surface area is 314sq.cm
