For the first question
The image grew bigger the new triangle is bigger than the original one
The scale factor is 3 by finding the length of
CA prime divided by Regular CA
The formula for the volume of a cone is (1/3)*area of the base * height.
The base is a circle, whose area is pi times radius^2. Here this is pi *
(r^2) = 3.14*(72 / 2 yd)^2 = 4069.44 yd^2. And so the volume is (1/3) *
4069.44 yd^2 * 24yd = 32,555.52 yd^3. I recommend that you find the
most common formulas of the geometrical figures and make a flashcard
that you can use at any moment.
30 students
14 have no siblings
that leaves 16 with siblings
6 have brothers and 12 have sisters which = 18 so 2 of the students have both a brother and a sister
2/30 students have a brother and a sister
1/15 chance
Answer:
1385.28 m²
Step-by-step explanation:
apothem = √16² - 8² = √256 - 64 = √192 = 13.86
Base area = 3 x 16 x 13.86 = 665.28
6 side area = 3 x 16 x 15 = 720
surface area = 665.28 + 720 =1385.28
Answer:
it is 20% your welcome
Step-by-step explanation:
because when you divide 100 by 2 its 50 so its 20%
