Volume of this cone

Mathematics
1 answer:
ArbitrLikvidat [17]3 years ago
7 0

Answer:

669.9 ft³

Step-by-step explanation:

The formula for volume of a cone:

v=\pi r^2*\frac{h}{3} (3.14*radius*radius*\frac{height}{3} )

r = radius,\pi =pi,h=height.

The radius is 8; the height is 10.

From here, we can just plug the numbers into the formula.

\pi 8^2*\frac{10}{3} (3.14*8*8*\frac{10}{3} ) = 669.866666667.

669.866666667 ≈ 669.9.

Which expression can be used to find the surface area of the following square pyramid
mariarad [96]

Answer:

a. 36+15+15+15+15

Step-by-step explanation:

The base of the pyramid is a square. We know that all sides of a square are equal so if we multiply the two sides of the base square(6*6) we get 36.

The area of a triangle can be found with the formula (b*h)/2. If we input the given values of 5 and 6 into our equation, then (5*6)/2 is 15 and since there are 4 triangles in the square pyramid, you multiply 15 by 4 (or add 15+15+15+15), and add the 36 from the base square.

Hope this helps :)

Help its for math will give brainly Find the area of the hexagon.
borishaifa [10]

Answer:

the area of the hexagon is 68 cm²

Step-by-step explanation:

Let us observe the image a little, we can find the area of the hexagon equals to the area of the large rectangle minus 4 small triangles surrounding the hexagon. The area of the rectangle is 8 × 12 is 96 cm². The area of 1 small triangle is 4 × 3.5 ÷ 2 = 7, there are 4 triangles, so the total area is 4 × 7 = 28. So the hexagon's area is 96 - 28 = 68 cm²

Hope this will help❤️
