Formula- A = π r²
a= area
r= radius
diameter of the circle- 3.75 x 2 = 7.5
hope this helps :)
We know that
lateral area=3*[area of a equilateral triangle]
Applying the law of sines to calculate the area of a equilateral triangle
Area=(1/2)*a*b*sin C
a=4
b=4
C=60 degrees
area equilateral triangle=0.5*4*4*sin 60-----> 0.5*4*4*√3/2---> 4√3 units²
lateral area=3*[4√3]----> 12√3 units²
the answer is
12√3 units²
5L:25Seconds=1L:5seconds
In 50 seconds there will be 10L of water
In 45 We will have to subtract 1L because we are exceeding 5 seconds and in 5 seconds 1L of water comes out
10L-1L=9L
There will be 9L of water
Solve each of the "equations"A. 10+ (5*24) = $130
B. 5+ (10*15) = $155
C. 0+ (15*9) = $135
D. 20+ (10*12) = $140
So choice A is the best
