Answer:
210 cm^2
Step-by-step explanation:
Let, a=37 cm, b=35 cm, c= 12 cm
s=(a+b+c)/2 = 42 cm
Δ=
Δ= 
Δ=210 cm^2

Step-by-step explanation:
hope its correct!
Answer:
50 softballs
Step-by-step explanation:
Volume of a sphere = (4/3)*π*radius³
A bowling ball has a radius of 8.5/2 = 4.25 in
Volume of a bowling ball = (4/3)*π*4.25³ = 321.56 in³
Circumference of a circle = 2*π*radius
radius of the basketball = Circumference/(2*π)
radius of the basketball = 29.5/(2*π) = 4.7 in
Volume of the basketball = (4/3)*π*4.7³ = 434.9 in³
radius of the softball= 12/(2*π) = 1.9 in
Volume of 50 softballs= 50*(4/3)*π*1.9³ = 1436.55 in³
A golf ball has a radius of 1.7/2 = 0.85 inches
Volume of 48 (four dozens) golf balls= 48*(4/3)*π*0.85³ = 123.48 in³
Answer:
1) √10 units
A=(-1, 0) let us assume (x1, y1)
B=(2, 1) let us assume (x2,y2)
distance= √(x2-x1)^2 + (y2-y1)^2
=√(2+1)^2 + ( 1-0)^2
=√3^2 + 1^2
= √10 units
