Answer:
6541.7 mm³ (nearest tenth)
Step-by-step explanation:

Given that the height is 40mm, h= 40mm.
Diameter= 2(radius)
Radius of cone
= 25 ÷2
= 12.5mm
Volume of cone

= 6541.7 mm³ (nearest tenth)
The correct answer is a || move the constant over (5x=-15-5), combine like terms (5x=-20), divide both sides by 5 to get x alone (x=-20/5), solve (x=-4) || please mark brainliest
The solution is 5*125/25 = 25
m=25
