Radius r = 1.
Step-by-step explanation:
Area of MNOP = (√2π)^2 = 2π.
Area 1 = Area 2, so
2π = 2πr^2
Dividing both sides by 2π:-
r^2 = 1.
r = 1.

Answer:
x³ + x² + x
Step-by-step explanation:

= x³ + x² + x
"The perimeter of a triangle is 294cm. The sides are x + 2, 2x + 3, and 3x + 1. Find the length of each side of the triangle."
Answers
Answer:
50cm, 99cm, 145cm
Step-by-step explanation:
The perimeter is just the distance around the triangle. We have all three sides.
So
(x+2) + (2x + 3) + (3x + 1) = 294
Combine like terms
6x + 6 = 294
Subtract 6 on both sides
6x = 288
Divide 6 on both sides
x = 48
So the sides are
x + 2 = 48 + 2 = 50 cm
2x + 3 = 2(48) + 3 = 96 + 3 = 99 cm
3x + 1 = 3(48) + 1 = 145 cm
Checking, first:
50 + 99 + 145 = 194 cm
Plug in x = 48 to the original equation.
48 + 2 + 2(48) + 3 + 3(48) + 1 = 294
48 + 2 + 96 + 3 + 144 + 1 = 294
294 = 294
The lengths of the sides of the triangle are 50 m, 99 m, and 125 m.
What is the perimeter of a triangle?The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.
The sides of triangle are x + 2, 2x + 3, and 3x + 1.
Given that the perimeter of a triangle is 294 cm
Since the perimeter of a triangle is the addition of the lengths of the triangle's three sides.
So the perimeter of a triangle = sum of all sides
⇒ x + 2 + 2x + 3 + 3x + 1 = 294
⇒ 6x = 294 - 6
⇒ x = 288/6
⇒ x = 48
So the length of the first side = 2+48 = 50
So the length of the second side = 2(48 ) +3 = 99
So the length of the second side = 3(48) + 1 = 125
Thus, the lengths of the sides of the triangle are 50 m, 99 m, and 125 m.

crate had 140 red apples, which
were 70% of the apples in the
crate. How many apples were in
the crate?
Answers
Step-by-step explanation:
140/70=2 Therefore, 1 apple equals 2 percent
The remaining 30 percent times 2 equals 60
60 apples plus 140 apples equals 200 apples
Answer B
Answer:
200.
Step-by-step explanation:
70% is equivalent to 140
10 % .............................. 140/7 = 20 apples
100% ................................. 10*20 = 200.
