Answer:
D is true
Step-by-step explanation:
A, B, C, and E are supplementary pairs so they cant equel each other.
The slope formula is the difference of the y values over the difference in the x values. We have a slope, so we will fill in the formula with what we have and then solve for x:

. Multiply both sides by x-10 to get rid of the fraction. -2(x-10) = 4. Distribute to get -2x+20=4 and -2x = -16. That gives us an x value of 8.
Answer: C 6 cm
Sorry if I’m wrong
I think you have multiply 5x4 which equals 20 then 20 divided by 10 which equals 2 and that’s ur answer
Answer:
total surface area of cone is πr (r+l)
22/7 x 3 (3+4)
22/7*3 (7)
22 x 3 ( as 7 that was divided by 22 was cut out with 7 in the bracket)
hence,
TSA of cone = 66pi
