The diameter of a circle is 6 centimeters. What is the circle's area?<br><br> Use 3.14 for pi

Lynna [10]

Step-by-step explanation:

diameter=

$2 \times\pi \times r = 6 \\ r = \frac{6}{2 \times 3.14} = 0.955 \\ area = \pi \times {r}^{2} = 3.14 \times {0.955}^{2} \\ = 2.87\: {cm}^{2}$

The volume of a cube is 7.14 cubic meters. What is the cross-sectional area that is parallel to one of its faces?

Snowcat [4.5K]

Answer:

A = 3.706 square meters

Step-by-step explanation:

the length of a cube has equal side.

therefore, the volume of a cube is given by S³

V = S³ = 7.14

where S is the length of a side

the surface area of a cube is = 6S²

where the area a aside is calculated, then it is multiply by 6.

if S³ = 7.14

S = ∛(7.14) = 1.925 m

What is the cross-sectional area that is parallel to one of its faces?

this is saying we should calculate for the cross-sectional area of one face. All faces in a cube is equal and parallel to each other.

the crossectional area of one side of a cube is = S² = 1.925² = 3.706 square meters

A = 3.706 square meters
