The standard formula for the circumference (C) of a circle in terms of its diameter (d) is ...
... C = π·d
The formula of a lateral area of a triangular prism is
LA = (1/2)*(perimeter of a triangle)*h
The perimeter of a triangle is the total of all sides.
Since the length of the base of a triangle is not given yet, use the Pythagorean theorem
base² = 7² + 24<span>²
base</span><span>² = 625
base = 25 cm
The perimeter is 7 + 24 + 25 = 56 cm
Finally the lateral area is
LA = (1/2)*56*30 = 840 cm</span><span>²</span>
Answer:
My work keeps getting deleted because apparently I am not aloud to share a graph link but I can try to message you it.
Step-by-step explanation:
I can explain it, though. To find it, you must know where the points are! If you know that, i think you're good to go :D
.558 is rounded to the nearest thousandth
Area is given by the formula
Area = length*width
Filling in the given information, we have
51 = (2m+7)*(m-2)
2m² +3m -65 = 0
(m -5)(2m +13) - 0
m = -13/2 or 5
Since dimensions of physical objects are non-negative, the value of m is 5.
