7^{2} + 7^{2} = C^{2}
49 + 49 = C^{2}
98 = C^{2}
9.8 ≈ C
10 ≈ C
C = hypotenuse
Answer: C
128pi
Step-by-step explanation:
v=(pi)(r^2)h
A circle has full round angle of 360 degrees. A circle represents all survey participants. We need to find the total number of survey participants.
total = 174 + 122 + 55 + 19 + 130
total = 500
Then determine the measure of angle represents people selected football using information above.
football =

football =

football =

football =

football = 87.84⁰
to the nearest whole number
football = 88⁰
The measure of angle represents people selected football is 88⁰ (b)
Answer:
196.1
Step-by-step explanation:
Area of a circle is
so in order to find the radius you divide the diameter by 2 to get 7.9
Then you do
x
to get around 196.1
when multiplying two binomials together we use the F.O.I.L. method:
First
Outer
Inner
Last
(7-3i)(2-i)
First: 7 * 2 ..... Outter: 7 * -i .... Inner: -3i * 2 ...... Last: -3i * -i
First: 14 ...... Outter= -7i ..... Inner: -6i .... Last: 3i^2
putting this together we get 14-7i-6i+2i^2
We combine like terms and end up with 2i^2-13i+14
