Find the area of the circle whose diameter is 68 cm​

Mathematics
1 answer:
postnew [5]3 years ago
4 0

Answer:

1156πcm²

Step-by-step explanation:

Diameter = 68cm

Therefore radius = 68 ÷ 2 = 34cm

Area of a circle = πr²

= π × 34cm × 34cm

= π × 1156cm

= 1156πcm²

NOTE: In case you're given the value of pi, substitute it into the formula to get your answer

This is on my homework, can someone help me? TwT
Zinaida [17]

Answer:

$221

Step-by-step explanation:

Hello!

The total cost s $627.83, for one desk that costs $185.83, and two identical chairs (c).

The equation: $185.83 + 2c = $627.83

This equation represents the cost of the desk plus two chairs of the same price, which adds up to the total price.

Solve for c:

  • $185.83 + 2c = $627.83
  • 2c = $442
  • c = $221

Each chair, c, costs $221.

In the picture below, ABCD is a rectangle. If the area of triangle ABE is 40, what is the area of the triangle?
MariettaO [177]

Area of the rectangle: 112

Step-by-step explanation:

Picture is missing: find it in attachment.

The area of a triangle is given by

A=\frac{1}{2}bh

where

b is the length of the base

h is the height

For triangle ABE, we know that

A = 40 (area)

h = 8 (height)

So we can find the length of the base AE:

AE=b=\frac{2A}{h}=\frac{2(40)}{8}=10

Now we observe that the base of the rectangle, AD, is the sum of AE and DE, therefore:

AD=AE+DE=10+4=14

We also know the height of the rectangle AB is 8, and that the area of a rectangle is

A=bh

where b is the base and h the height. Therefore, the area of this rectangle is

A=bh=(AD)(AB)=(14)(8)=112
