Remember to use SOH CAH TOA. Very simple. I ended up getting 18/17 as my answer
First find the volume of cone then the hemisphere and add them together.
V of cone = 1/3πr²h
V of cone = 1/3(3.14)(2)²(6)
V of cone = 25.12 cm³
V of hemisphere = 2/3πr³
V of hemisphere = 2/3(3.14)(2)³
V of hemisphere = 16.75 cm³
Volume of the whole figure = 25.12 + 16.75 = 41.87 cm²
Due to the answer choices it is closest to C. 42 cm³
Let x be the length.
Then the perimeter is given by the formula : 2(20+x)=40+2x.

Step-by-step explanation:
The diagonals of a parallelogram bisect each other. Since midpoints will be involved, use multiples of 2 to name the coordinates for B, C, and D.
Answer:
A
Step-by-step explanation:
4x^2-8x-60=0
a=4 b=-8 c=-60
*I am going to plug these numbers into the quadratic formula*
x=-(-8)plus or minus
*simplified into...
x=-8 plus or minus
x=5 or x=-3
