Question

1)FIND THE VOLUME OF:
a.Cube whose each side is 1.5 cm
b.A spherical ball whose radius is 7cm.

2)a. Find the area of a triangle whose base is 10m and height is 7m.​

Answer 1

Answer:

1) Volume =a cube = 1.5 cube = 3.375 cm cube .

2) Volume= 4/3 pi r cube

= 4/3×22/7×7cube .

= 1436.76cm cube .

3) Triangle =1/2×base ×height

Triangle = 1/2×10×7

Triangle = 35 m square .

Answer 2

Answer:

1.) a.) answer in the attachment photo.

b.) answer in the attachment photo.

2.) a.) Given :

• Base (b) = 10m
• Height (h) = 7m

To find :

• Area of triangle = ?

We know that :

Area of ∆ = 1/2 x b x h ( base x height)

= 1/2 x 10 x 7

= 35m^2

Hence :

Area = 35m^2.
