Answer:
Those are two different questions that aren't related isn't it?
Step-by-step explanation:
I KNOW
Area = base x height /2
Base =26.5
Height =40
26.5 x 40 /2 = 530
Answer:
10a = 30
Step-by-step explanation:
By using elimination:
4a + 2z = 10
-2(3a + z) = -2(-10)
4a + 2z = 10
6a - 2z = 20
2z and -2z cancel out
10a = 30
a = 3
They are asking for 10a, so 10 (3) = 30.
Hey there! Your answer is right here!
42 ÷ 2 = 21 ÷ 2 = 10.5
Thanks for asking this question. I'm glad I can help!
Answer:
253.5π
Step-by-step explanation:
Surface area of cylinder: 2πrh+2πr^2
Height: 13, Radius: 6.5
A = 2π6.5(13)+2π6.5^2
A = 169π + 84.5π
A = 253.5π
