Area = 2pi*r*h + 2pi*r^2
Area = 2pi*r(h + r)
radius of 7 in and a height of 32 in
Area = 14pi*39 = 546pi in^2
The sum of the internal angles in a simple pentagon is 540°.
105 + 135 + 92 + 87 = 419
540 - 419 = 121
The angle is 121
Answer:
B
Step-by-step explanation:
Any number, regardless of its sign, raised to an even power will always be positive. Therefore, a⁷² will be positive. We know that -3/7 is negative, and since a positive times a negative is negative, the answer will be negative.
let the number is 10x + 3.
then sum of its digits = x + 3.
from given condition, we have
x+3 = (1/7)* (10x + 3)
=> 7x + 21 = 10x + 3
=> 3x = 18
=> x = 6
therefore the number is 63.
X = -(-1) +/- sqrt((-1)^2 - 4*4*3)
------------------------------------ = 1/8 +/- sqrt47i
2 * 4
None of the choices are correct
