circle for 8 is 2 and the square is 4
circle for 12 is 2 and the last circle is also 2
Answer: slope = -7/8
Step-by-step explanation:
Slope = (y2-y1)/(x2-x1)
= (9-16)/(9-1)
= -7/8
Answer:
Step-by-step explanation:
From the picture we find that the sphere and the cylinder has equal heights.
i.e. cylinder has height = 2r.
x,y and r form a right triangle with hypotenuse as r.
Hence pythagorean theorem is satisfied
Area of the cross section parallel to it is area of circle with radius y
=
Volume of cylinder when 2 cones removed =
Hence volume of sphere =
I'll be using the formula for area of a circle. because based on the given image the cow can graze 1/4 area of the circle.
100 ft rope will be its radius.
Area of a circle = π r²
A = 3.14 * (100ft)²
A = 3.14 * 10,000 ft²
A = 31,400 ft²
31,400 ft² x 1/4 = 7,850 ft²
7,850 ft² or 2,500 π ft²
Answer:
False, 6:4 and 18:8 are equal ratios.
Step-by-step explanation:
Given data:
6:4 ≠ 18:8
Explanation.
1. 6:4 = 6/4 = 3/2
2. 18:8= 18/8 = 9/4 = 3/2
Hence proved:
6:4 = 18:8
