Answer:
372
Step-by-step explanation:
area of trapezium = a+b/2 * h
a is the length on top
b is the length on the bottom
h is the height
7+24/2*24=
=372
9514 1404 393
Answer:
207.24 in²
Step-by-step explanation:
The "r" in the formula stands for the radius of the cylinder. That is half the diameter, so is 3 in. The "h" in the formula stands for the cylinder height, shown as 8 in. Put these values in the formula and do the arithmetic.
SA = 2πr(r +h) = 2(3.14)(3 in)(3 in + 8 in) = 6.28(33 in²)
SA = 207.24 in²
Answer:
See below.
Step-by-step explanation:
(5a^2 + 4ab – 3b^2) – (–5ab + 4b^2 + 3a^2)
5a^2+4ab-3b^2+5ab-4b^2-3a^2
(5a^2-3a^2)+(4ab+5ab)+(-4b^2-3b^2)
2a^2+9ab-7b^2
-hope it helps
Step-by-step explanation:
