Answer: The hieght is 12.7 inches
Step-by-step explanation:
r=d/2
3.5/2=r
r=1.75
v=pir²h
122.5 =piR²h
122.5=pie1.75²h
The frist thing to solve for r sense exponents come before multiplication in bedmask
122.5 =pi3 .06g
so then it's pie times r
122.5=9.61 *h
122.5/9.61=h
12.7=h
Answer:
A. 31.84
Step-by-step explanation:
Since ms perry is greater, u subtract 40.44 by 8.6 giving you 31.84
You are finding the surface area of a triangular prism
The advanced formula is bh+2ls+lb which gets you 266.6
Or you can do it the long way... so imagine a triangular prism... a square/rectangle on the bottom and both left and right (3) and 2 triangles on both sides connecting all of the rectangles together... calculate the area of one of the rectangles and a triangle and multiply the triangle by 2 and the rectangle by 3 then add to find the surface area
The correct answers would be a b and 2 because I don’t know this is a test to be honestly
