Answer:
r = -3
Step-by-step explanation:
- 60= - 24 + 12r
Add 24 to each side
- 60+24= - 24+24 + 12r
-36 = 12r
Divide each side by 12
-36/12 = 12r/12
-3 =r

Given : Radius of cylinder = 8 m
Height = 4 m
Volume of cylinder = πr²h cu. units
= 22/7 × 8 × 8 × 4 m³
= 804.57 m³ (approx.)
Curved surface area = 2πrh sq. units
= 2 × 22/7 × 8 × 4 m²
= 201.14 m² (approx.)
Total surface area = 2πr(r + h) sq. units
= 2 × 22/7 × 8 (8 + 4) m²
= 2 × 22/7 × 8 × 12 m²
= 603.43 (approx.)
Let the first number = x
The second number would be 5x
The third number would be 100x
Add:
X + 5x + 100+x = 296
Simplify:
7x + 100 = 296
subtract 100 from both sides:
7x = 196
Divide both sides by 7
X = 196 / 7
X = 28
First number is 28
Second number is 28 x 5 = 140
Third number = 128
D because all the other ones are postive d is the only negative one so it can’t be any other one
Answer:
3 digits because 4641/39 is 119.
