Answer:

I. Base area = 35 cm²

II. Volume of rectangular prism = 350 cm³

Step-by-step explanation:

Given the following data;

Length = 7cm

Breadth = 5cm

Height = 10cm

a. To find the base area of the rectangular prism;

Base area = length * breadth

Base area = 7 * 5

Base area = 35 cm²

b. To find how much it takes to fill the rectangular prism, we would need to determine its volume.

Volume of rectangular prism = length * breadth * height

Volume of rectangular prism = 7 * 5 * 10

Volume of rectangular prism = 350 cm³

c. To find the answers to the other part of the question, we would determine the capacity of the prism in litres.

Capacity = volume in cm³ to litres

1 centimeter = 0.001 litres

Capacity = 350 * 0.001

Capacity = 0.35 litres.

If the blue radius below is perpendicular to the green chord and the segment BC is 7.6 units long, what is the length of the cho
galina1969 [7]

Answer:

The correct answer is A. 15.2 units

Step-by-step explanation:

The segment AB is congruent to the segment BC  eg AB≅BC Why?

We can prove it with the triangle congruent theorem, postulate side-side-angle

We are watching triangle ΔABO and triangle ΔCBO, they are congruent

first element side OB=OB - common side

second element side OA=OC=r - radius of the circle

third element angle ∡ABO≅∡CBO=90°

According to the postulate side-side-angle we can conclude that triangles

ΔABO≅ΔCBO (triangles are congruent)

If they are congruent all of their elements are also congruent and therefore also

side AB=BC  => AB+BC=AC,  which is chord  => 7.6+7.6=15.2 units

AC= 15.2 units ( chord )

Good luck!!!
