Answer:
Correct
The solution is Sarah; The pi button on the calculator gives a more accurate representation for pi than 3.14. Using 3.14 as an approximation for pi yields a less accurate result.
Step-by-step explanation:
Answer:
Step-by-step explanation:
→ Find the LCM of the denominators (2,4 and 8)
LCM = 8
→ Multiply the whole equation by 8 to get rid of the fractions
4x + 6 = 7
→ Minus 6 from both sides to isolate 4x
4x = 1
→ Divide both sides by 4 to isolate x
To work out the volume of a prism, you multiply the area of cross-section by the height (or length).
So for a cylinder, you work out the area of the circle and then multiply it by the height.
Area of circle (or cross-section) = π × radius²
= π × 0.7²
= 0.49π m²
Now to get the volume of the cylinder, you times this area of the cross-section by the height of the cylinder:
Volume = 0.49π × 1.5
= 2.3 m³ (accurate to 2 decimal places)

Answer:
2.193 and
Step-by-step explanation:
Area of Segment = πr²θ/360 -½r²sinθ
=π*3²*85/360-½*r²sin85
= 2.193cm²
volume of cone= ⅓πr²h
=⅓*π*3²*21
=198 cm³
