Answer:
37.68 units³
Step-by-step explanation:
To calculate the volume of a cone, the formula is:
V = π x r² x ( h / 3 )
Simply input the corresponding numbers into the equation:
V = π x ( 2 )² x ( 9 / 3 )
V = π x 4 x ( 3 )
V = π x 12
V = 3.14 x 12
V = 37.68 units³
If we use 3.14 for pi, the answer comes out to 37.68 units³
Side length = 16.7 cm
Solution:
Perimeter of a square given = 66.8 cm
In a square four sides are equal.
The perimeter of a square = 4 × side
⇒ 4 × side = 66.8 cm
Divide both sides of the equation by 4 to equal the expression.
⇒ side = 66.8 ÷ 4
⇒ side =
⇒ side = 16.7 cm
Hence, the side length of the square is 16.7 cm.

Step-by-step explanation:
Answer:48.6
we know that
You can paint 75 square feet of a surface every 45 minutes
so
using proportion
Find out how long it takes you to paint a surface area of 81 square feet
45(81)/75=48.6
hope this helped and I hope you get a correct answer :D
Answer: The speed of the motorboat is 70 miles per hour
Step-by-step explanation: Subtract the initial distance, 35, from the distance at any given time, then divide the remainder by the hours.
For example, at 2 hours, the distance shown on the graph is 175 miles
Subtract: 175 -35 = 140. Then divide 140/2 = 70
At 4 hours, the distance shown is 315 miles.
Subtract: 315 - 35 = 280. Then divide 280/4 = 70
70 mph is the speed.
