<u>Answer: </u>120
Since there is the 100 in the triangle, the other two sides in the triangle are equal to each other. So they are both 40
So 180 - 40 = 120
Answer:
I believe it is because it does not start at 0
Hello!
The equation for a circle is

(h,k) is the center
r is the radius
Put in the values you know

Simplify

The equation is

Hope this helps!
Answer:
250π
1000π
Step-by-step explanation:
(refer to attached)
volume of cylinder is given by:
V = π r²h,
where r = radius of base and h = height of cylinder
Given r = 5 and h = 10, hence
V = π r²h
V = π (5)²(10)
V = π (25) (10)
V = 250π (answer)
For the second case, r = 10 cm
V = π r²h
V = π (10)²(10)
V = π (100) (10)
V = 1000π (answer)
#2
Change mixed numbers to improper fractions. Then change division to multiplication by the reciprocal.
1 1/2 divided by 3/5=
(3/2) * (5/3) = 5/2 = 2 1/2
#3
(5/9) divided by (5/3)
(5/9) * (3/5) =3/9 = 1/3
