First you have to know the formula, which is a=p*r^2.
next you have to fill in the info which is 3.14*16 or A=50.24
so the answer for the area is 50.24 Ft
hope this helps have a great day
pls give brainliest
Step-by-step explanation:
(2a+3b)(4a²-6ab+9b²
(2a+3b){(2a)²-2a×3b+(3b)²}
Because (a³+b³)=(a+b)(a²-ab+b²)
Therefore,
(2a+3b){(2a)²-2a×3b+(3b)²}
=(2a)³+(3b)³
By substituting the values , we get
- (2a)³+(3b)³
- (2×3)³+(3×(-5))³
- 6³+(-15)³
- 216+(-3375)
- 216-3375
- -3159
Answer:
the angle is 245°
Step-by-step explanation:
that is a pentagon, (a shape with 5 sides)
we know 4 of the angles in the pentagon
the sum of those 4 angles is
58°+100°+112°+25°=295°
to find a shapes total amount of °, the equation is (n-2)x180°
(5-2)x180°
=540°
540°-295°=245°
x=245°
The answer is o+ Hope this helped.
