Answer:
20/3
Step-by-step
(base1+base2)/2 * height = area of a trapezoid
64/12=16/3
16/3*2 = 32/3
32/3-4 = 20/3
Answer:
112
Step-by-step explanation:
180 - 40 - 28 = 112
X/6 + 7 = 20
subtract 7 from each side
x/6 + 7 - 7 = 20 - 7
x/6 = 13
multiply each side by 6 to get x alone
x/6 • 6 = 13•6
x = 78
Answer:
I think the answer is C. 1209 cm^3
Step-by-step explanation:
volume of a cylinder= πr^r2xh
radius = 1/2xdiameter
r = 1/2× 9
r = 4.5cm
height. = 19cm
volume of the cylinder = 22/7 x (4.5)^2 x 19
= 1208.73cm^3
= 1209 cm^3 ( to the nearest whole number)
It is 27/6 or 4 1/2. you just need to subtract the numerators because you have a common denominator
