Answer:
3m^2+3
Step-by-step explanation:
Step 1: First you have your equation or something.
3m (m+1)
Step 2: You multiply the parenthesis with the number.
Step 3: Then 3m to the parenthesis if you have 3m and m will convert to m^2.
Step 4: Your answer would be 3m^2+3
Answer:
V = one-third pi (4 squared) (7) feet cubed
Step-by-step explanation:
Volume of cone v = 1/3×π(r²h)
r = 4 and h = 7
V = 1/3 × π(4²×7)
Answer:
Step-by-step explanation:
if 3 inches is ................................................2.5 miles
4.5 inches.................................................? miles
=4.5*2.5/3=3.75 miles
choice C
(B) 16.5π
<u>Explanation:</u>
The shape given is a cylinder
The height, h of the cylinder = 4cm
Diameter of the cylinder = 3cm
Radius, r = 1.5 cm
Surface area of cylinder, A = ?
We know:
Surface area of cylinder = 2πrh + 2πr²
Therefore, the surface area would be 16.5π
