Can someone please HELP ME!!

IRISSAK [1]

Volume of a cone = PI x r^2 x h/3

Volume = PI x 5^2 x 9/3

Volume = 235.62 cubic cm.

Volume of a block of wax = L x W x H

Volume = 2 x 4 x 3 = 24 cubic cm.

Total number of blocks = Volume of cone / volume of blocks:

235.62 / 24 = 9.82

Round up to 10.

They will need 10 blocks.

A farmer plowed a rectangular section of land for a new crop. The section measures 24 1/2 yd by 38 1/2 yd. Find the total area i

MAVERICK [17]

Answer: $943\dfrac{1}{4}\text{ sq. yds}$

Step-by-step explanation:

Given , A farmer plowed a rectangular section of land for a new crop.

Dimensions of the section is given by :-

Length by width = $24\dfrac{1}{2}\text{ yd by }38\dfrac{1}{2}\text{ yd}$

Since , the area of a rectangle = length x width

Then, the total area in yards of plowed section of land will be:

$24\dfrac{1}{2}\times38\dfrac{1}{2}\text{ sq. yds}\\\\=\dfrac{2(24)+1}{2}\times\dfrac{2(38)+1}{2}\text{ sq. yds}\\\\=\dfrac{49}{2}\times\dfrac{77}{2}\text{ sq. yds}\\\\=\dfrac{3773}{4}\text{ sq. yds}\\\\=943\dfrac{1}{4}\text{ sq. yds}$

Hence, the total area in yards of plowed section of land = $943\dfrac{1}{4}\text{ sq. yds}$
