A training field is formed by joining a rectangle and two semicircles, as shown below. The rectangle is 98m long and 76m wide. F
Vsevolod [243]
Without the image, I assume the two semicircles are on each end of the rectangle.

Rectangle; A = lw
A = 98 x 76
A = 7,448 square meters

Put the two semicircles together to form a circle; A = π2^{2}
A = (3.14)(76^{2})
A = 3.14 x 76 = 5,776 square meters

7,448 + 5,776 = 13,224 square meters

qaws [65]

Answer:

Around 1,500 pounds

Step-by-step explanation:

Because you said "estimate," I will be estimating this.

49% rounds up to 50%

3,025 rounds down to 3,000

50% of 3,000 is 1,500 pounds.

Rewrite: 72x3/4<br> please show how you got answer
Alex_Xolod [135]

We have been given the expression

72 \times \frac{3}{4}

We can rewrite the expression as \frac{72\times 3}{4}

In order to simplify the given expression, we can check if we have any common terms in the numerator and denominator.

We can write the term 72 which is in the numerator as 18\times 4

Thus, the expression becomes

\frac{18\times 4\times 3}{4}

We can see that 4 is common in both numerator and denominator. Hence, we can cancel 4. Thus, we are left with

18 \times 3\\&#10;=54

Therefore, we can rewrite the given expression as 54.
