Answer:
The longer side of the rectangle is 25 yards.
Step-by-step explanation:
The area of a rectangle, A = 100 square yards
The perimeter of a rectangle, P = 58 yards
We formula for area and perimeter of a rectangle is given by :
A = lb
and
P = 2(l+b)
ATQ,
lb = 100 ...(1)
2(l+b) = 58
(l+b) = 29 ....(2)
We need to solve equation (1) and (2).
l = 4, b = 25
So, the longer side of the rectangle is 25 yards.
60% more than regular size. 230.4.
Answer:
irrational
Step-by-step explanation:
If you picture a cylinder rolled out flat. there would be two circles for top and bottom and then a rectangle for the side. The rectangle would have width equal to height and length equal to circumference.
So then the areas of the pieces are added together to get total surface area.
= 2pi(3x-2)^2 + 2pi(3x-2)(x+3)
and you can simplify this is you want by multiplying through and combining like terms.
= 2pi(12x^2 - 5x -2)
or factor more to simplify the solution.
= 2pi(3x-2)(3x-2+x+3)
= 2pi(3x-2)(4x+1)
Answer:
∠ PRQ = 55°
Step-by-step explanation:
The angle subtended at the centre by an arc is twice the angle subtended at the circumference by the same arc, thus
∠ PQR = 0.5 × 110° = 55°
