Answer:
The correct options are a,b.
Step-by-step explanation:
The area of sector of a circle equals
Area of a sector = 
where
is the angle subtended at the center by the sector
is the radius of circle
This indicates that area of the sector depends on:
1) Radius of circle
2) Angle subtended at the center by the sector
3) Area of sector does not depend on pi.
Also if we know the area of the sector only we cannot calculate area of area of whole triangle as we need one more information either angle of the sector and vice versa.
Answer. multiply 13 and 64 then round to the nearest tenth

Answer:
The lateral surface area of the cone is 
.
Step-by-step explanation:
We have.
Height of a cone is 60 m
Diameter of a cone is 10 m
Radius, r = 80 m
The lateral surface area of a cone is given by :
l is slant height of the cone,
Plugging all values in above formula,
So, the lateral surface area of the cone is .
Answer:
0.14
Step-by-step explanation:
Using the poisson probability relation :
P(x = x) = (λ^x * e^-λ) ÷ x!
From the question ; mean, λ = 5 ; x = 3
Hence,
P(x = 3) = (5^3 * e^-5) ÷ 3!
P(x = 3) = (125 * 0.0067379) / 6
P(x = 3) = 0.8422375 / 6
P(x = 3) = 0.140
