Answer:On a scale drawing of a steel I-beam , the height of the beam is 2 1/2 in. The scale is 1/4 in = 6 feet. What is the actual height of the I-beam. \(12\)
Step-by-step explanation:
Find the area of the top, which is a circle.
Area of a circle = pi x r^2
Area = 3.14 x 1.5^2 = 7.065
Now for the volume multiply the area of the top by the height:
7.065 x 12 = 84.78 cubic inches
Round to the nearest tenth: 84.8 cubic inches
Answer: The "?" would equal 1.
Step-by-step explanation: This is simply a line with a slope of 1 and a y-intercept of zero.
Answer:
Option B. 2376 Square feet
Step-by-step explanation:
The following were obtained obtained from the question:
Base (B) = 24ft
Length (L) = 40ft
Height (H) = 9ft
Slant height (S) = 15ft
Surface Area (A) =?
The surface area (A) for triangular prism is given below:
A = BH + 2LS + LB
Where:
B is the Base
L is the Length
H is the Height
S is the Slant Height
A is the Surface Area
Using the above equation, the surface area can be obtained as follow:
A = BH + 2LS + LB
A = (24x9) + (2x40x15) + (40x24)
A = 216 + 1200 + 960
A = 2376 ft2
