y = 23/8
Please correct me if I'm wrong!! :)
Well, you are trying to simplify the numbers and the equation. You are trying to get the smallest possible number or solution. A difference between the two is that polynomials have factors and variables. Numbers are just numbers. With a polynomial, you have to combine like terms and try to reduce the length of the equation. You may not always fully solve a polynomial. With numbers, you probably will get an exact numeral answer.
Answer:
73.2sq.in
Step-by-step explanation:
Area of the triangle = 1/2 * base * height
Get the height using the pythagras theorem
h^2 = 13^2 - (13/2)^2
h^2 = 169 - (6.5)^2
h^2 = 169 - 42.25
h = 11.26in
Area of the triangle = 1/2 * 13 * 11.26
Area of the triangle = 6.5 * 11.26
Area of the triangle = 73.2sq.in
Hence the area of the triangle to nearest tenth is 73.2sq.in
Answer:
B
Step-by-step explanation:
Formule for volume of cone:
V=πr2h
(Disregard the pi, Multiply the radius and height)
9 × 9 × 12
81 × 12
972
972π sq. units
