Answer:
3/110 sq. ft.
Step-by-step explanation:
Area = 3/22 x 1/5
= 3/110 sq. ft.
Answer:
Step-by-step explanation:
There are several possible outcomes. If your cross section is created by intersecting the cone with a plane parallel to the base of the cone, the cross section is a circle. If the plane is held vertical, the cross section could be a hyperbola. If the intersecting plane is neither vertical nor horizontal, the cross section could be an ellipse.
Answer:
62m³
Step-by-step explanation:
The question is incomplete. Find the diagram of the prism attached below.
Volume of a Prism = Base area × Height
Given height = 9m
Since the prism is a triangular based prism,
Base area = area of the equilateral triangle = 1/2bh
base of the triangle = 4m
Height can be gotten using Pythagoras theorem.
Slant side of the triangle is the hypotenuse = 4m
Adjacent = 1/2 of the base = 1/2(4)= 2m
Height = √4²-2²
Height = √16-4
Height of the triangle= √12 m
Base Area = 1/2×4×√12
Base Area = 2√12 m
Volume of the prism = 2√12 × 9
= 2×2√3×9
= 36√3 m³
= 62.2m³
Volume of the prism is approximately 62m³
Since Ellen drove a total of 80 miles, and for 2 hours.
Her speed is = 80/2 = 40 miles/hour
So Ellen drove for 40 miles/hour.
Since Carin drove 5 miles per hour faster than Ellen, the he drove = (40 + 5) = 45 miles/hour.
So Ellen drove 40 miles/hour and Carin drove 45 miles/hour
