Question

The height of a cone is 14 cm and the area of its base is 321 cm square. Find the volume. ​​

Answer 1

Answer:

v = 1496 cm^3

Step-by-step explanation:

Height: 14 cm

Area of base: 321 cm^2

Volume of cone= (1/3)πr^2h

Area of base:  πr^2

π = (22/7) (in this cause we will set pi = 22/7)

we just need to find the radius to plug it in to the volume formula

πr^2 = 321 cm^2

(22/7)r^2 *(7/22)*(321cm^2)

r = (102cm^2) ^ (1/2)

r = 10.995..cm

r = 10.10 cm

Volume = (1/3)πr^2h

h = 14 cm

r = 10.10 cm

v = (1/3)π(10.10cm)^2(14 cm)

v = 1496 cm^3

Answer 2

Answer:

Cells are the basic building blocks of all living things. ... Cells also contain the body's hereditary material and can make copies of themselves. Cells have many parts, each with a different function. Some of these parts, called organelles, are specialized structures that perform certain tasks within the cell.
