Answer:
Area of a circle- <em>pi </em>x <em>r </em>square
3.14 x 2 x 2
= 3.14 x 4
= 12.56
Round off- 13
Answer:
Step-by-step explanation:
For compound interest, we use the formula A = P(1 + r/n)^{nt}, where A is the amount, P is the principle, r is the rate, n is the number of times compounded per period of time, and t is the time.
We can alter this for a decrease. Instead of adding r/n to 1, we can substract it:
A = 17,600 * (1 - 0.01175 / 1)^{1 * 11} = 15,454.24
After 11 years, the car will be worth $15,454.24
Answer:
Given: An Angle in the figure is right angle. Its measure = 90°
So,
∠2 = 90° ( vertically opposite angles are equal )
∠1 + ∠2 = 180° ( Linear Pair )
∠1 = 180 - 90
∠1 = 90°
So, ∠1 and ∠2 are
Right angles because measure of both angles are 90°.
Adjacent angles because both a common arm and a common vertex.
Supplementary angles because sum of both angles is 180°.
