Answer:
785.0cm³
Step-by-step explanation:
Formula of calculating volume of a cylinder
= π r²h (Pie × radius square × height)
Radius given = 5cm
Height given = 10cm
working: π × radius²× height
= π × 5² × 10
=785.5398
=785.0cm³ (3s.f)
Answer:
10v^2
Step-by-step explanation:
(I'm assuming the 2's are all exponents)
3v^2 - 2v^2 + 9v^2 <- think of it as 3 - 2 + 9 = 10, then add the rest back on
10v^2
Answer:
C) No solution
Step-by-step explanation:
Because we know that y=3x-2, we can substitute the value of y into the first equation to get x:
-6x+2y=-6
-6x+2(3x-2)=-6
-6x+6x-4=-6
-4=-6
However, there is one problem! Since both sides are not equal to each other, there's no solution. Therefore, C is the only correct answer.
Answer:
250.35
Step-by-step explanation: pythagorean theorem
215^(2)+x^(2)=330^(2)
46225+x^(2)=108900
x^(2)=62675
x=5√2507
x=250.35
