Answer:
Step-by-step explanation:
reqd.area=area of square ABCD + area of trapezoid(or trapezium)CEFG
BE=BC+CE=16+16
CD=CG+GD=8+8
A=16×16+1/2 (16+8)×16
=256+192
=448 sq. inches.
or
reqd. area=32×16-1/2(8×16)
=512-64
=448 sq. inches.

Solving for h = 4r
Answer:
356.8cm3
Step-by-step explanation:
Volume of a cone= 1/3 * base area * height.
Note: don't be confused by right circular cone ; a cone is gotten from a cylinder by dividing it into three parts. One from the right vertex slanted to the middle of the base; another from the left vertex slanted to the middle of the base and the remaining portion with the surface base at the top.
Going forward; base area =pi * raduis * raduis [ area of a circle; the base is a circle]
Volume= 1/3 * (3.142 * 7.8 * 7.8 *5.6) = 356.83cm3
Volume= 356.8cm3 [ to the nearest tenth].
Tenth means 1/10= 0.1; that is value after the decimal point.
Answer:
1. The y-intercept is 10
2. The slope-intercept is -2
Step-by-step explanation:
1. The y-intercept is 10 because when the x-intercept is 0 the y-intercept should be on the other side.
2. (2,6) and (-1,12)
slope=rise/run= the change of y/the change of x=m=y2-y1/x2-x1
1. change of x=-1-2=-3 and change of y= 12-6=6
2. 6/-3= -2
hope this helps <3
