Answer:
area of the sector = 360π cm²
Step-by-step explanation:
To calculate the area of the sector, we will follow the steps below;
First write down the formula for calculating the area of a sector.
If angle Ф is measured in degree, then
area of sector = Ф/360 × πr²
but if angle Ф is measured in radians, then
area of sector = 1/2 × r² × Ф
In this case the angle is measured in radiance, hence we will use the second formula
From the question given, radius = 15 cm and angle Ф = 8π/5
area of sector = 1/2 × r² × Ф
=1/2 × 15² × 8π/5
=1/2 ×225 × 8π/5
=360π cm²
area of the sector = 360π cm²
Answer:
88 
Step-by-step explanation:
Given 3 measurements 6,11,4
Assuming them to be length, width and height of pyramid
⇒
Length= 6 cm
Width= 11cm
Height= 4 cm
⇒
Therefore Volume of Given Pyramid
=
⇒Volume of pyramid=88
