Answer:
C
Step-by-step explanation:
The cakes which overlap are the small and middle & the middle and large. The total area of overlap for these cakes will be the surface of the smallest layer's base plus the surface of the middle layer's base.
We can find the area by where r is radius which is half the diameter.
Smallest cake - D=7.5, so r=3.75
=10.5625 × π = 33.1830724035 or 33.2
Middle Cake - D=10, so r=5.
=25 × π = 78.5398163397=78.5
We add together 33.2+78.5= 111.7 cm squared
C is the closest.
6 divided by 66739 equals 11123 with the remainder of 1. Hope this helped!!
Answer:
B. 4 square feet
Step-by-step explanation:
The formula for area of a triangle is length x height / 2 so 4 x 2 is 8 then divided by 2 is 4.
Answer:
24 units^2
Step-by-step explanation:
A=1/2*b*h
A=1/2*4*12=1/2*48=48/2=24
Answer:
26.68 ft
Step-by-step explanation:
Let a represent the distance from Kelsea to the bird and b be the distance from Landon to the bird.
Let x = angle of the bird. Hence:
x + 45 + 20 = 180 (sum of angles in a triangle)
x + 65 = 180
x = 180 - 65
x = 115°
Using sine rule:
Let h = height of the bird to the ground. Since a right angle is formed. hence:
