Step-by-step explanation:
This will form a hollow circular part of a cylinder of outer radius 7cm and inner radius 3cm
Area of a circle is given by πr^2.
Then, the big circle of radius 7cm
Area= πr^2
Area=22/7×7×7
Area =154cm^2.
Area of the circle of radius 3cm
Area= πr^2
Area=22/7×3×3
Area =28.286cm^2.
Area of the shaded part becomes
Big area - small area
154-28.286
Area of shaded part = 125.7143cm^2
Then to the nearest hundredth
Area of shaded part =125.71cm^2
Answer:
7/3
1
1/2
undefined
Step-by-step explanation:
1/1 ÷ 3/7 = 7/3 because you multiply the 1st fraction by the reciprocal of the 2nd
1/1 = 1
1/2 = 1/2
1/0 = undefined; anything divided by zero is considered to be undefined
Answer:
No ,not anything ,hahahahaha
The amplitude is 3
for a sine graph, the amplitude is the distance up or down from the midway point. The equation to find the amplitude is (max-min) / 2.
(3 - (-3)) / 2 = 3
